Third Party Exclusives are dying on all platforms. Not just the PS3.

On all HD platforms.  Exclusives are still common on DS, PSP & Wii.

yep! even sony knows it! i remember reading an article years ago where sony said 3rd pary exclusivity is going out and it falls to first party to make a system valuable (or something like that) and thats where sony wins! then again nintendo has a pretty good first party but microsofts first party is quite week so.... YA

TL;DR 3rd party exclusives = dying

3rd pary exclusives are going multi just look at wii ports, bungie and insomniac going multi for evidence.

if a game is published by microsoft or sony it is 2nd party.

i can't believe i actually read 5 pgs of this stupid thread

at this point in time its better for sony to start buying more gaming companys
