Okay so I just saw the trailer... 

My question is PC or PS3?

Hmm, I would say PS3 only because Sony stuff, should always be played on sony software! :)

haha might be a good way to build on my trophies as well

Pretty much, plus I think in terms of VGC, you will find more users who paly DC universe on the PS3. 

Twesterm said the PC version has less bugs so you might want to ask him.

PC

1.  It simply runs better.

2.  The PS3 crowd won't commit, over the next year the very good PS3 lineup will take away their attention and the PS3 crowd will dwindle.  The game does not allow cross platform play.

PC, always go with PC for MMO's man.

hmm these arguments make sense... trophies will have to suffer.

Cheers for the response guys

now i dont have the game nor played it BUT what i have herd is that it was made for PS3 and the menus and action buttons suite the ps3 better

but ur second point does make sense

What if you have a Sony PC?

lol
