I suppose they'll never include MMS functionality, I suppose what other users said about them "not believing in MMS" is a reason for that. A missed chance, some might say.
About the video recorder... they might have put that in if they'd included a better camera, but as far as I understand it, the iPhones photo capabilities have never been one of its parade features, and I suppose Apple doesn't intend it to be either. If they added video recorder functionality they may have had to top up the camera too for image reasons, which they were obviously not prepared to do this time around.
