I think that they're making them smaller... judging by the iSights that come installed into the MacBook Family.
For those of you who are talking about the iSight built into the displays... how would that work... some displays sit up pretty high (especially the 30") and the camera would completely miss the person unless they moved the display or themselves. If they angled the camera downward, how do they know that everyone sits in the same exact spot? It's not like tilting a laptop display back an inch. I sit a couple of feet away from my display but, others may sit closer or whatever. It just doesn't make sense to have a birds eye view of the person.
