If you didn't already know, here's the link to some casual SCV matches running 24/7 on XBL - http://www.twitch.tv/8wayrun247

As I don't own both version of the game yet, I wanted to know if there was any major difference between the 2 versions of SCV for X360 and PS3. I found this and it seems that the game looks and plays almost identical on both platforms (even input lag seems identical).
