Retrofocus does better on digital because it is more telecentric by design. The advantage of rangefinders was that such designs could be avoided, but that was when people were shooting film. Digital sensors all have filter stacks, so even with microlenses, you are always going to have problems with traditional short flange wide angle designs due to the light angles. This is why the original 4/3 format required all lenses to be telecentric, since that is ideal for digital. Of course, with m4/3 olympus decided that such a requirement isn't as crucial and has relaxed the standard a bit.
As for Sony, which has proven over history to be one of the most anti-consumer electronics manufacturers ever, all I can say is that they make great sensors and its a real shame that their photography products are such a unfocused mess. Every new product (NEX, A7, etc) is innovative indeed, but they don't seem to have any real long term strategy other than throwing new products out there because they think they will sell. They built up a fairly large lineup of alpha lenses and now the future of alpha mount looks fairly doubtful over the long term. They created the Nex platform but don't really seem to have any interest in building a lens system around it. Now Nex is no more and is merged with alpha, which brings us to the A7. At this rate sony is producing far more new bodies and mounts than actual lenses. Compare this to Fuji, who is still a very niche player and in a rather short time has built a nearly complete lens system for its X series of cameras. Fuji has a clear strategy and seems committed to their offerings. Sony just looks like a big question mark to me to be honest.
