I pointed this out in the A7 poll thread as well, but I do think Thom has a legitimate point when he says "if you bring out a new system and start from scratch with lenses, so can everyone else". Maybe not Olympus, given their financial situation, but there's not much stopping Nikon, Canon, Fuji, etc from competing with Sony on this front. What unique advantage does Sony have other than first mover status?
Not sure if Nikon can come up with what Sony has done, they are too conservative in their thinking. Canon perhaps, but for one problem, they want to do everything in-house and have slipped on the technology side.
I don't know about Fuji.
Regarding lenses, one simply has to look at Nikon's V1 series, it started out with only two lenses, so how does this differ from what Sony has done? Also, Sony has the advantage of a "universal" (almost) mount...
