The timing is right for me. I've been wanting/needing a second body, both as a back up and so I can have 2 cameras simultaneously ready to shoot with different lenses mounted. Spring/summer is approaching which is when I tend to do most of my bird photography. So I went ahead and pre-ordered one, even though I view the D7200 as a very minor update and not much better than my D7100 in most ways. A deeper buffer and slightly improved AF (hopefully not
only improved in low light). The sensor may be different but they didn't even mention a "new" sensor, so I'm not expecting any significant improvement in high ISO or dynamic range. I'm glad the sensor still lacks an OLP filter. I'm convinced that doesn't hurt and maybe sometimes it helps capture a tiny bit more resolution. Built-in WiFi is nice too, but they need to improve the phone app to give us better remote camera control.
Call me crazy, but because this camera clearly doesn't even try to compete with the 7DII, I still think a truly pro DX body eventually may still appear... If I wasn't really wanting/needing a second body right now, I would probably wait. If a pro DX body finally does happen, then Nikon will have played me perfectly, and this D7200 might quickly become my back-up / second body.
Nikon is still "holding back" when it comes to high-end DX, continuing to try to force people switch to FX, or possibly saving room for an upcoming pro DX body (or both). Nonetheless, for bird photography, the improved buffer and AF system makes this D7200 an even more compelling alternative to the D810, especially for someone who is limited on funds; it lets you put those extra $$ into the lens.

PS. Here is a link to open a handy comparison for D7100 vs. D7200. In some of the original announcements it sounded like the latest "Group" AF mode was not included, but this says it is. Also some sources show a very slight difference in body size/weight, but they are listed the same on this sheet. I think they are pretty much exactly the same size and take the same grip.
