There is no way this Tamron is going to be F2 at 70 mm, unless it's way bigger then it looks to be. Not to mention it would make their 28-70/F2.8 kinda pointless (yes i know 35 isn't 28 but still) I will be very happy if it goes till like 50 mm with F2 and maybe like 65 mm with F2.5. I'm really looking forward to this lens either way.
If we go with the existing 35-150mm f2.8-4, it has these aperture transitions:
35 = f/2.8
50= f/3.2
65 = f/3.5
105 = f/4.0
So add a stop of light to those and you get:
35 = f/2
50= f/2.2
65 = f/2.5
105 = f/2.8
I would not expect them to both add a stop AND keep the max aperture for a greater range at the same time.
Still very exciting. You get faster than any standard zoom from 35-104mm. 35mm f2, 50mm f2.2, 85mm f2.5, 100mm f2.5 and 135mm f2.8 all in one lens will be amazing for any portrait photographer. Leave a whole bag of primes at home.

Yup, that's exactly what i said, this lens can't get released soon enough (for me insta buy). Even if the F2.8 is earlier in the range than we expect it still gonna be amazing. With T17-28 or even better GM 16-35 in the bag you get everything (if you dont do birds) with excelent F2-2.8 throu the whole range with just 2 lenses.

Welp, it is going to be hard not to buy this lens.
I'm in the process of rebuilding my kit after selling everything off. I thought I decided to go with a few batis lenses, 40 and 135 in these ranges, but this lens would replace both with more reach on both ends and everything in between AND at the same max aperture . Those 2 lenses weigh ~1kg, which this lens likely will as well and will probably take up the same size in a bag.
So, something is going to have to be seriously wrong with this lens for it to not make sense for my uses.

I thought it was a typo when I first saw it, these specs are incredible. I know it will be a pretty large and heavy lens, but this seems like a portrait photographer's dream. Also seems like a fantastic alternative to a 70-200 2.8 (hell even Tamron's own 70-180 makes little sense in comparison). I expect them to sell a large number of these things.
My 24-105 probably won't be going anywhere as it's already as large as I'd like to carry around, but wow this Tamron is enticing.

This lens has definitely has my interest. But I want to see how well it fares against flare that's my main concern with every lens I get. But it could make a nice there lens kit with the 14 gm and 24 gm as I don't like lugging around the 100-400 much and would have prefer a 70-200 but the f4 sony version isn't the best lens although it is light and compact.

With the exception of the size issue...this thing could sorta/kinda replace my Tamron zooms of...28-200 & 70-180.
The one I'd be most on the fence about selling would be the 28-200, it's a great range in a small package. As for the 70-180, it gets used a lot for volleyball, where courtside 70 is sometimes a little tight, and with 61mp to play with the difference between 150mm & 180mm is negligible to me.

The 200-600 doesn't breathe while focusing and that always requires a focal length reduction. Tony Northrup conflates breathing and focal length reduction. Those concepts are related but mutually exclusive instead of identical.
Internal zooms do not require focal length reduction. Many extending zooms lose more focal length when focusing than non-breathing lenses. These are all different things.
So what is breathing?
As for the rest of what you've written, it seems to run contrary to what these shooters found in their testing. First video speaks to it at about 25:20, and the second video is an expansion on what was tested.
It just seems so quickly after the original, and that didn't have that much wrong with it? (apart from built quality and features). Is this just a quality upgrade all around or did Tamron find some sort of breakthrough?
MTF's are out for the new lens, good improvement from mid frame to corners and 75mm is much better it seems. Faster AF motor better close focus too. I had no interest in the current version already owning Canon 24-70 f/2.8L II, but this might tempt me to update.

In fact the focal length changes!

In what scenario could your angle of view change without the focal length changing? I get that angle of view is measured from the lens' optical center to the subject and focal length is measured from the optical center to the image plane, but the two are interdependent, no? The shorter the focal length, the greater the angle of view. The longer the focal length, the narrower the angle of view.

Think about your eyes. Do you experience your angle-of-view changing while refocusing? Your eyes focus by squishing a soft lens. Squishing that lens changes its focal length/optical power. Your eyes don't push a fixed focal length lens out. Luckily, your eyes don't have a fixed focal length lens. They focus by varying the focal length of a lens that doesn't move axially. The result is that you don't experience optical breathing.
Focusing by extending a fixed focal length optic results in a narrowing of the angle-of-view which is breathing.

There are rumors going around that Tamron is going to set the price of 35-150 F2/2.8 at 2000-2200$. Imo that's quite high and will be a non-starter for many people if true. Thou i probably still gonna buy it.

MTFs looks good. Big question in my mind with this 35-150 and the new 28-75 is how is the bokeh? I'm glad they're updating the 28-75, hopefully the bokeh is not so harsh.

Depends on the performance. If I find it acceptably sharp throughout most of it's range, I would part ways with my 55/1.8 and 24-105/4. Maybe, just maybe, my 100/2.

Yeah that's the logic most people go by. Buy this Tamron and get rid of 2-3 lenses they use now. It's the same for me, thou i think most people thought it's gonna be a bit cheaper (again if rumors are true).
. Those 2 lenses weigh ~1kg, which this lens likely will as well and will probably take up the same size in a bag.
