WnN2 - Thank you.
Mohamed_GANgsta - Not a dis, just lay off the over sized text.
Granted this only speculation, but if R* has a plan w/ the exclusive 360 DLC, it's probably to get the PS3 owners to want it that much more. For all we know, Sony wants to hold off so they can charge a premium if/when they finally do get DLC.
R* could've also been looking at Sony's initial release of the PS3 as a shortage or something. Remember people camping out at Wallmart & the insane prices they sold for on e-bay?
Previous titles had exclusive release but eventually released to other platforms.
As I said, only speculation.
