My 2 priorities:

1 - Option to have cropped images fill the viewfinder

2 - The ability to actually use studio flash! Although I never envisaged using the Q2 with studio flash when i purchased it, when my Nikon D800 just failed i was hugely disappointed to find that it seems impossible to use the Q2 for a studio shoot, because the viewfinder (showing the actual exposure preview) is too dark to compose with. Could this feature be turned off? (I've read that it can be in the SL)

Certainly it is. Compressed DNG? (Lossless or not?) To what end, please? In your opinion, what might the trade-offs be? Thank you for hanging in here with your query. It is interesting.

Um, to save space on the card and in storage. Lossless compression isn't hard, just do zip. Optimized lossless compression is harder. :)

I don't know the Q2 well yet, and don't own one ... yet. But from what I see: The ability to completely turn off image review in all drive modes is the biggest priority for improvement that I see. I don't want to review the last pic I made immediately; I want to be ready for the next pic immediately. 

Second priority would be optically matched front-element wide and tele converter auxiliary lenses. I'd like the ability to get close to a 21mm lens and a 105mm lens field of view occasionally, the latter with about 10 Mpixel resolution.

I get only 1% space saving by zipping a .dng

That suggests that the .dng files are already losslessly compressed. :)

Zipping an uncompressed DNG file from other cameras has resulted in 20-40% reduction in size.

While I have no doubt that is true, if you pass a Q2 DNG file through the Adobe DNG Converter using "Don't use lossy compression" the file size reduces by approximately one-third...so it can be done.

The Adobe DNG lossless compression is much much more efficient than zip compression. Adobe doesn't recommend it for in-camera use because it is very compute intensive and really requires a much higher level of compute capability.

Yet the images from my M 262 are compressed out of camera.   Typical size is about 25 MB vs 40 MB for my Q.   Saving metadata changes in Lightroom compresses the Q image down to the same 25 MB that the M delivers.

I suspect the issue is one of speed.  Burst mode frame rate will suffer when compression is used.  My M burst rate is only 3 frames/sec; the Q "high" option is reported to be 10 frames/sec.  This is not an issue for me (I keep my Q on the low setting) but may be an issue for others.

According to the Macfilos site, the issue is likely processor heat ..

1)Video - Full Manual Mode

2)Video related -  Enable Bluetooth to be used for accessories (microphone, headphones)

3) Improved Dynamic Range at high iso - minor nit

4) Agree with Mike (macfilios) on ability to lock buttons to avoid the wandering focus point problem.
