Ooh, that's a very poor update imho.
I can't see any major features to make anyone with a D7100 in a rush to upgrade. And anyone who held off buying the D7100, I can't see much to nudge people to now make the move.
With the D7***, and the lack of a D300S replacement, it seems more obvious than ever that Nikon wants anyone who wants high fps, (and the large buffer to go with it) better user interface, more rugged build to go FF.
Me, with a D300S, I'm considering going for the 7DII and a change of brand. The D7200 is not even close to changing my mind about that option.
