i dont think sony will have a problem when it comes to exclusives in their first year.
-naughty dog (uncharted team) released UC3 in 2011, so by 2014 they would have had enough time to release a new game
- media molecule LBP2 released in Q1 2011, also enough time to make a game by launch or launch window
-sucker punch infamous2 mid 2011, so a mid 2014 release window is likely is well
- santa monica, if they really are two teams now they had since Q1 2010 to release make a game, that would be about 4 years
- Guerrilla Games - reportedly a two team studio as well now, making killzone 4 and a new IP. killzone3 released in Q1 2011 so thats about two and half years to release a game and more time to release the other
- Ready At Dawn, they made the Two GoW games on the PSP and are now making a "next gen" game. it was said before that its an action adventure tittle, GoW ghost of sparta released in 2010, so they would have had more than enough time to make their game by launch date
these are six very talented studio's that can make diverse games and big hits. each one of them also released their last game at either 2011 or 2010 so they had enough time to make exclusive games set to release within the first year of the PS4
