if any game company drops out its going to be sony they've lost over 3 billion dollars because of the ps3 and i also think the share holders will force them out
who will replace them id a difficult question i think either apple,Activision Blizzard,sega or Atari
appel becuse there trying to get iphone and itouch in the handheld industry they may see a opportunity to jump ship and make a home console
Activision Blizzard because they have so many Ips it may justify making a home console
sega and atari they've made consoles in the pat and this may be the best time to make a new one
