Hmm, at twice the price of the Samyang, it's gonna be a hard sell in the crowded region of 85mm I think.. Especially considering SY has this special something in the images it produces and it's sharpness is pretty exceptional (at least to me).
Well, maybe we will get GM's beautiful bokeh balls and rendering with Sigma sharpness and snappy AF at 2/3 of GM price .

If this lens has the same kind of across-the-field sharpness as their FE 85mm 1.4 ART, with the much smaller size/weight, I'm in!
Of course, the resale value of my current ART lens will likely be less than favorable after the announcement of this lens... not that ART lenses have great resale values to begin with.

Although the Sigma 85/1.4 Art E-mount is way bigger (152mm vs 94mm in length!!) and twice as heavy as the new DG DN E-mount (1,245g vs 630g!!), based on their optical designs, there is a chance they perform will similarly.
Optical design comparison:
Sigma 85mm f/1.4 DG E-mount: 14 elements (2 SLD, 1 APD and 1 ASPH)
Sigma 85mm f/1.4 DG DN E-mount: 15 elements (5 SLD and 1 ASPH)
The 85/1.4 DG E-mount was announced in Sept. 2016, so it's a fairly new design but if the new DG DN matches its performance, it would be an outstanding accomplishment.

I expect that part of Sigma's past design formula for the amazing technically performing 40mm, 85mm, 105mm & 135mm (I have shot all of them) is a large image circle that they can then crop for great edge performance and low vignetting. The current 85mm ART lens is 86mm and the new one will be 77mm.
Of course, the latest technology lens grinding machines, allowing tighter tolerances & more complex shapes, six-sigma processing and more complex lens design software seems to be allowing this great "flat" performance with smaller lens openings as demonstrated on Sony's GM 135mm and even the Sigma 35mm f1.2... and, hopefully, this new Sigma lens.
This is a great time to be buying camera lenses for finicky equipment nerds such as myself.

Similar price (given new release), and similar complexity, no doubt better optical selections, and the key feature: a dramatic reduction in size and weight. A small wager says it also delivers better performance as the third piece of the trade off.
Sound engineering consists of a careful and judicious balancing of user needs - lens makers would never realise this if they were not forced into it, it's a process still underway.
'Every lens made by anyone balances three things: price, size, and image quality. Sigma has made their attitude clear; size can be damned; we’re going to make reasonably priced lenses with amazing image quality. If they’re huge, they’re huge. That’s what I expect from all the Art primes.' LR blog
It was never what I expected from a committed competitor. The earlier lens was quite literally a case of burden shifting from the maker to the buyer. Now, after a market-induced attitude adjustment it's been reversed - as it should be! Much better, kudos to Sigma.

Would that be only at 1.4, or also at other apertures?
Sadly the lens is a little more pricey than I expected. I'll stick with my Sony 85 1.8.
Wide open the aperture should not be visible. The design and number of blades should only be of consequence when stopping down. I use 'should' here because owners of some unnamed Zeiss lenses may beg to differ about how visible the aperture is wide open...
The rumoured Sigma looks well priced for what it is. It continues Sigma's record of undercutting Canon/Nikon/Sony by at least a few hundred dollars. The Sony 85/1.8 continues the trend of 85/1.8's in general...being excellent performers and even more excellent values

The new Sigma 85/1.4 DG DN Art for mirrorless has the advantage that the optical engineers didn’t have to design around a mirrorbox. This time around Sigma has the same or even better flexibilty that Leica has always had when designing rangefinder lenses for the Leica M system, always without regard for a required minimum back focal distance (Schnittweite) that would have been required by a mirrorbox. So can this new Sigma 85/1.4 compete with the Voigtländer 75/1.5 or the Summilux-M 75/1.4 in pleasing imagery?
Another feature I notice is that the new Sigma 85/1.4 has got an aperture ring like the 45/2.8 and 35/1.2. Even Sony has carried this trend forth to the 20/1.8 G.

Honestly I wanna know what this drop proof feature is all about
I've heard them refer to their barrels as damage resistant before and something about a plastic they were using that was more flexible than the conventional stuff.
But I don't see how that will mitigate alignment issues when dropped, so I'm really keen on a good elaboration of that point also 👍

I've been lead to believe that "drop proof" should have been written as "drip proof", because SAR admin is a neanderthal who couldn't type without errors for more than 2 sentences if his life depended on it.

It would be an instant buy ;-)!
Looking forward to this lens and hope for great iq in a small form factor.

Don’t be fooled into thinking it will make the lens better withstand the consequences of a fall from any height
Yes, the earlier reports of the lens being dropproof appear to be a mistranslation. I believe a better translation would be water resistant.

I recently sold my Sony 85mm f/1.8 for the Samyang f/1.4 lens so when I seen this at first I felt a bit conflicted. The only Sigma lens I kept for a long time was the 50mm and 85mm f/1.4 EX lenses.
I was wondering if I should have waited but considering it will probably be around $1600-1800 AUD at least, it will be way too much for me to pay when I got the Samyang.

I expect this new, smaller design to exhibit quite a bit more vignetting. Going for the Sony style of "lightweight but with multiple stops of vignette even when you stop it down a little, and who cares, we'll fix it electronically in the lens profile". That's just a guess, but we'll see.
There's no absolute right or wrong with different lens design tradeoffs. I am grateful that Sigma has provided a bunch of lenses that are exceptionally good optically, and that provide reduced vignetting at a cost of greater weight. I think it's good that they made that option available. It took nothing away from anyone that they did so. If someone wants lighter lenses there are many available, and more all the time, this one included.
I agree optically the old 85 might be about as good as the old 85 if all goes well. But it would be hard to imagine exceeding its performance. Autofocus speed - sure. Character of the out-of-focus areas - sure, it'll probably be different somehow. But as I said before, the old 85, like the 135, is exceptionally sharp and clean already. Among the best of the Art lineup.
That said, I couldn't believe Sony's 135mm could possibly turn out to be sharper than the Sigma 135, and yet it did (albeit to an extent that was not important, given how close the Sigma already was to flawlessness).

That makes so much more sense. As far as I know, the only "drop proof" lenses are those from Leica (and all makes of cinema lenses): they are so expensive that you take extra special care to avoid letting them slip out of your hands. It works.
