I like that it's not on PC because it means EVE Players are less likely to just play both and for the wars to be influenced by the same real-life people. Splitting them up makes it so different player-bases are influencing things in one universe. Pretty neat. Also I'm pretty sure one of CCP's main motivations for it being PS3 exclusive was upfront money from Sony. Not sure but I remember hearing something similair when Dust 514 was announced as PS3 exclusive.
