Full backwards compat with games and XBLA titles (if they didn't do these, that would probably be the biggest slap in the face imho) along with achivements means day one purchase of the system for me.
The other things that they should work on is console reliability and backwards accessories (I know, keep dreaming but that SF4 TE stick was expensive!).
It's just that simple.
