The Nikon D7200 was announced last week
Nikon D7200 Digital SLR Camera | DSLR from Nikon
Two views possible:
1. Minor upgrade to the already excellent D7100 with a few improvements - bigger buffer so you can do long bursts of raw, latest autofocus, better sealing, Wifi
2. It's the D400 at Dxxx price
I've gone for view 2
Sold my D7100
Ordered the D7200
The D7100 has been a great complement to my D800 when I needed something smaller, lighter, cheaper. I hope that the D7200 will have an advantage for action and really low light situations
