Nice list Henrik! Funny, but I think what appeals the most to me from your list would be an APS-C GRD. FF would be very cool, but I have my doubts they'd keep it similar in size to the RX1. And I'd rather see FF applied to a RF lens compatible GXR module. So, a compact APS-C with a decently fast, very sharp, wide lens (good for cropping, a la digital zoom) would be great. Hopefully it would also keep the price reasonable, since such a camera would probably serve a secondary grab n' go purpose, rather than as a main camera, for many.
And i agree about the NEX-6. I had a look at one the other day and it appears Sony have finally addressed one of my peeves about the NEX UI. It looks like one can reassign the AE-L button to a number of uses, including manual focus assist (i.e. zooming), which places this critical function (if using adapted lenses) in a much more thumb-friendly shooting location. I've recently been using a borrowed NEX-7 and it's a major UI pain the butt trying to reach the lowest function button in order to zoom in for critical focus (the focus peaking, IMO, is unreliable for critical use).
As an aside, unfortunately I find the NEX-7 a more complementary camera to my Leica system than the GXR. The massive pixel density of the 7, coupled with my longer RF lenses, gives me much more reach for those times when I'm focal length limited with the M9. While the GXR M module has higher pixel density than the M9 cropped to APS-C, it's not a big difference. For me, the GXR's benefit is that it's a great overall camera to use with any of my RF lenses, especially wides, as a 'system' back-up to the M9, or for use on its own. But, I have to admit I'm somewhat let down by having 'only' 12MP to work with. This is more so the case when working with wide angle lenses and high detail scenes, where fine details tend to quickly take on a jaggedy-edged quality. In the recent RF 21mm lens shootout I did, I did a smaller subset comparison with the GXR and NEX-7. Take those NEX-7 files and down-rez them to 12MP and they're really impressive. Zero jaggedy edges. And with a touch of sharpening, extremely highly detailed.
As Michael points out, it could be that the NEX-6 is the best NEX compromise for use with wider RF lenses. It's good enough for edge quality, while gaining the integrated EVF and improves on some UI over the 7. And to my eyes, the EVF looks a bit better than in the 7 too. It feels slightly bigger.
For my purposes the debate would be whether the UI improvement of the 6 offsets the 7's higher pixel density, for my uses alongside the M9.
Matt: nice car! I thought domestics were mandatory ownership in Michigan? Seems it's about all I see when cutting through the state on road trips.
