The way he is hyping it up my guess is that it's Bungie or Valve making a PS3 exclusive. Bungie deal with Activision is for 1 franchise and I'm sure they are allowed to make other games for other companies. Valve could do PS3 and PC and that would remain an exclusive.
I too am wondering about Sony's and Nintendo's numbers. I don't want any predictions I want solid numbers. Some people pegged 360 sales at 600,000 but obviously they were wrong. I bet the 3DS sold amazingly, up here in Canada the system was $139 and during my trips to stores mom's were going crazy buying them. Literally every other person at the Toysrus I went to had a 3DS and some games.
