I don't think that will push Sony over the top, but more importantly: why is cross-game chat so coveted?
Being able to communicate with friends and teammates playing the SAME game makes perfect sense. But why is it so important that I can chat with my friend while I play Halo 3 and he plays Crackdown? Shouldn't we be immersed in our games?
If it's just about a free way to chat with friends over long distances, there's always Skype.
