Lately the BF3 commercials I've been seeing are for PS3 and the MW3 commercials I've been seeing are for 360. Is it just me or is PS3 not promoting MW3 as much due to MW3 sales and DLC favoring more towards 360?

Thoughts?

EA always pimps the PS3 version and Activision the 360 one. Been like that for a good 2 years or more.

Years ago Microsoft made some kind of cross-promotional deal with Activision for Call of Duty.  Then Sony made a similar deal with EA for Battlefield.  There's not really anything unusual about it.  At the end of just about all video game commercials you will see the logo of one console or another.  It shares the costs of advertising between publishers and console manufacturers, and benefits both parties.
