HDR in built capability would be wicked. I have recently stolen my girlfriends D200 and been messing around with HDR stuff.

Also great for timelapse....

Agree with you on the 24p and 30p.... why don't they just give it the ability to do the whole host of frame rates, the technology is obviously there? That is one of the biggest critisims about the 5D MkII is that your stuck on 30p.
