Frame rate seemed fine to me. They say it is the same as "the other console versions", which at this point is only the 360. If true it supports 4-player split screen, 8-players online and 4-player split screen with 4 online. I'd like to know if I can buy it once, install it on both of my PS3s, then play 2-player split screen on both for 4 players together online in the same house (there is no lan support).
Update: Bought it last night. You can play splitscreen or install on two PS3s and play co-op, I think it just lets you join friend's maps if they have it open. They can set it to invite only. The weird thing is you need an online enabled account to join, even for split screen. So I tried to log in with my daughter's account while I was playing and it said she is not allowed to play online games, but it was just splitscreen! So that strangness aside, the game is intact, the frame rate is fine. Even the skin support is in, I bought the holiday skins for $0.99.
