Rockstar Keen To Push PS3 Copies?

Looking over the recent ads and murals spotted in LA & New York it's interesting to note the cover ad and from what I can see the Trevor mural as well advertise only the PS3 version of the game despite the game being released for XBOX 360 as well.

The likely reason is that Sony is involved in the funding of the ads or it could mean that Rockstar is keen to push the PS3 version of the game for whatever reason. Let the speculation begin! Either way it's great to see the ads and murals popping up.
