I didn't necessarily expect any. Years where new systems are shown off tend to be of the non-surprise variety outside of the systems themselves. If there were surprises they probably would have been announced early on today via Press Release...I haven't seen much outside of:
Stranglehold for PS3 and Xbox 360 (at least) - John Woo directs and Chow Yun Fat stars in an action game coming in 2007 from Midway
Brothers in Arms: Earned in Blood - although this was known to be coming, I am surprised it will be out before the end of the year
MGS4 and MGA2 unveiled (well, MGS4 "trailer" probably wasn't shown with PS3 technology)
Alan Wake (Gamespot's reaction to showing
) and Prey (Gamespot's reaction
) shown in ATI booth - these look nice, although Prey's showing is not anywhere I've seen as of yet
I am a bit surprised that Blizzard didn't announce a new game, but that's covered in another thread.
