Just found an interesting announcement on sony.net about lens compensation:
Apparently there will be a very promising App for the expected problems which third party (manual) wide angle lenses will inevitably cause:
lens cast / color cast will probably be correctable in camera for each programmed lens individually!
As you can also type in lens name, focal length and f-stop, I expect this to appear in the exif data - would be great! (Leica: Please take note...)
At this point it is not clear if those corrections (Sony calls it “peripheral shading”) only apply to jpg or raw as well.
And obviously it's not just vignetting but especially individual color corrections: One should be able to correct for the green / magenta color cast towards the corners.
In addition chromatic aberrations and distortion will be correctable separately as well!
More questions arise about the amount of corrections so I expect to spend quite some time fine tuning each profile to achieve good results.
Not that I found the handling of the Sony apps (on my NEX6) very compelling so far, but as long as I will be able to build my own profiles and correct those imperfections (in the new A7 and A7r) I would be very happy.

Scroll down to the "Play Memories Camera Apps" and find a short video (go to 10"), screen shot attached.
While we wait for delivery: Go out and shoot with what you’ve got and ask yourself if you really need (more) new gear...
As for me, I do
