Improving the JPG quality would be great, as I'm sure there are significant numbers of people who would care about that (maybe not so many of us, as we all shoot RAW, but I believe a lot of people will use JPG even with a camera like the A7).
Regarding lossless RAW and "how hard could it be", as others have pointed out, the way they have implemented the compression it probably saves their processor from doing some work, EG saves on internal bandwidth in a few places. They might not be able to support lossless RAW, at least not on the A7R. And it's done at a pretty low level (perhaps even hardware, as wfrank pointed out).
If they go lossless, I don't think it'll happen with the existing hardware. It'll be the next rev of the camera itself.
