if it were the PS network, I'd be down. why is it whenever bands do this, they use XBOX Live? Playstation 3 is clearly the superior gaming machine.
Oh, and...Last i checked PS3 doesn't *yet* have a game that provides anywhere close to the online experience of Halo 3.
I also disagree with your overall assessment of PS3 as a gaming machine....again, for now...until the software catches up. Same went for 360 in its early stages.
