It seems the PS3 and PC servers are separate (which is daft). Will suck, if say, the PS3 servers get low. Best bet is to go with PC version since PC users are more likely to adopt the game longterm, compared to console players.
From what I am reading also, content is perhaps very slim (even when compared to other new releases). Combat is also pretty fast paced, which is a nice change, but you guessed it, latency will slap you around if you connection sucks.
*Edit* Gah! May have to at least give this a try.
