* DOF preview button
* Possible FUNC button
* Front Command dial
* IR remote and wired remote
* SD card, not CF
* New AF button on top plate, probably selects something like Wide/Regular or Group/Dynamic/Single
* Top LCD illumination position on power switch
* D200-style diopter setting
* Some back, top buttons moved around
* New lens, definitely goes beyond 70mm (3-digit top number at top end). Lens looks ED and AF-S to me (that's an A/M switch you see), but NOT VR, so possibly 18-200mm AF-S. And it looks like it's the D50 kit lens type of AF-S (slower, no manual focus override).
