There are a number of game reveals that have been revealed to be present at the 2009 VGAs; Halo: Reach, Medal of Honor, Prince of Persia: The Forgotten Sands, Tron, UFC Undisputed 2010, and then some have all been announced to be a part of the show. But according to the show’s producer Geoff Keighley, the biggest surprises are yet to come. Surprises they couldn’t even pre-promote “because no one knows they exist yet.”

“We definitely have some pretty major surprises still to come,” he said in a recent chat. “Essentially, the biggest thing in the show hasn’t even been announced yet.”

While he didn’t even hint at what these games may be, he did say Dead Space 2 will not be among them — information from that one is limited to magazines only for the time being then.

The VGAs will air tomorrow night at 8PM Eastern.
