Oh ok I didn't know that you were specifically talking about the exclusive releases. But still there are some good titles that are/were exclusive for PC like Battlefield Play4Free, Diablo III and Star Wars: The Old Republic etc.
But what I don't understand is why bother for exclusive titles? As long as one is getting a multiplat title for his need, it should be good enough to go.
And if someone only likes the exclusive titles then he must go for PS3, as you mentioned in you post that PS3 uses a completely extra ordinary architecture in the form of its Cell Processor; So every time an exclusive title comes out for PS3 it should be great in all ways.
Please correct me wherever I'm wrong..
the Exclusive thing goes both ways
with Xbox360 or PS3 one can get all the benefits of Multiplatform games in addition to their line up of great exclusive titles
on PC u mentioned DiabloIII which is gonna be an excellent game
also Starcraft2 released in 2010 is arguably the best RTS of the decade
but most of our average gamers do not even know about these games
but Gears of War series on 360 or Killzone/MGS4 on PS3 will arouse interest in ur average gamer
im just saying Exclusives r an added benefit which consoles offer
and yes the Exclusives on PS3 and the amount of First Party support Sony has is an edge the PS3 has over the 360
all im saying is PC has lost its incentive for the average gamer
im sure "last_look" is gonna thoroughly enjoy either one of 360 or PS3 more than the PC
