I want to go get this game in like the next half hour or as soon as some of you help me decide?

What version should i get? I heard it was developed on PS3 and ported to 360? Does this mean it is slighty better on PS3? I mean does PS3 have slighty better graphics?

I heard some say it has some slow down? But then i heard someone with the 360 version say it runs smooth. So is it the PS3 version that has some slowdown and not the 360 version?

Also i know it has coop? Is it sever based? Like can i log on and just join a game with anyone? Or create a game and anyone see me game created and join? Or is it strickly for you have to envite someone already om your current buddy list? Also i know it has voice chat. And i think this will be essential for good coop play? With that said i feel maybe 360 and Live win for this? Can anyone confirm that most are using mics in PS3 version? And how is it?

you don't need 2 of the same topics... preferably in the Mercs 2 forum but whatever, I moved the other one to general discussions
