D7100:

I agree that there's more stuff that can be added to make it more 'desirable'
maybe a sport model with better than 6fps. Question .... how many fps do you need...with video and video capture, it starts to blur (pardon pun) into one.
longer battery life? they've got the extra accessory for the battery pack.
full weather protection. Those that get it will no doubt not only praise it but will have a wish list too.
i love the D7100 . I'll see whether there are any 'issues' like the D7000 had, but I doubt Nikon would make the same mistake twice. Definitely not their style.
