We should also consider any variations between the two versions. I know that the game has proprietary development teams for each system... And we have very little information to go off of so far. So correct me if I am wrong, but as of right now all we know is..
360 will have DLC in the future. which may sway some people who own both consoles to buy the 360 version. (+360)
360 will have achievements/ vibration in controller. So will PS3 - possibly by then.
I feel sort of cheap bringing this up, but hardware reliability could be a concern for buyers, since this game will be played for endless amounts of time by some people and the RROD is still running rampant in the 360 world.
Other things to consider once information is released is the small differences in graphics/ uncompressed audio/ online aspects/functionality.
with all of that being said, I think the 360 will sell way more in America, but the PS3 will sell more everywhere else. In the end the 360 will have the slight edge.
I expect either Sony or Microsoft or both to lower prices/ bundle the game to try and swing it in their favor though.
