I'm kind of blown away that there is going to be a game announcement on a late night talk show. I remember living in an age where video games were an obscure or niche hobby that instantly deemed you as geeky and uncool (...they still kinda do) and you never heard a mention of them from your non-gamer friends or the general public.
NOW its really popular and I'm seeing them everywhere. When I was watching the UFC 111 fight, every fight started off with "This fight is brought to you by God of War III, in the end, there will be only chaos." - and there was a Dante's Inferno commercial in the Super Bowl.
