Not a big fan of these deals, hated it when MS did it and though I game on PS, I still don't like it.
Also seems like a waste of money when Sony leading so much, but I guess it just pushes that agenda of being at the forefront of the gen, and I'm sure it'll help sell a few more consoles... so perhaps its not.
Anyway I am expecting MS to counter with some 3rd party games or purchases as they dont have the studios right now.... I think this E3 could be the most interesting and for all the wrong reasons.
