It's a week and a half away, people! The latest EGM is out and gave it a glowing review, emphasizing that the title's high point is its blurring of the line between the single and multi player components.
The 1UP podcast did mention that the PS3 version performs better but no mention of that made it into the review. Comparing the PS3 demo to the 360 demo myself I really didn't notice any difference.
Personally, I like the 360 version mostly because that means I can use the better controller and don't have to buy a bluetooth headset but since multi player is so important I'll follow the crowd on this one.
