Dunno if it's been mentioned already... (Not searching 12 pages
)....But I'd like to think that the GDC is going to keep with the modified sports motif, like soccer this past season. Dean himself at Kickoff said that he was "not afraid to do what's been proven to work already". I'm probably misquoting that, but you get the picture.
Considering that FRC keeps pushing for camera aided gameplay, I have a feeling we will be aiming at a target again in 2011, much the same way as 2010. Obviously, older games used the camera, but not quite in the same way. Bearing this in mind, the obvious sports that come to mind would probably be Hockey, Baseball, Football.
Or, the GDC could surprise us and go to something not-so-related to sports. It would follow a pattern... 2006 was basketball, 2007 was tic-tac-toe, 2008 was NASCAR, 2009 was...lunar exploration?, 2010 was soccer. According to this, it would seem that games that are similar to professional sports occur every other year. If that means anything at all, we're going to something different in 2011, and in that case, I have no idea.
