Is MW3 vs. BF3 Turning Into Xbox 360 vs. PlayStation 3?

Has anyone noticed something significant about all these Battlefield 3 vs. Modern Warfare 3 arguments?

The PlayStation 3 fans quickly turn to evidence from DICE and EA that the PS3 version of BF3 will be superior to the 360 version. They also mention EA's deal with Sony; all new content for BF3 will arrive on the PS3 one week early. At the same time, they claim most Xbox fans are only into shooters so unsurprisingly, the lemmenings will flock to any new Call of Duty . Plus, there's Microsoft's deal with Activision concerning the one-month jump on DLC for the 360.

So while both games are for both consoles in question, and the debates that focus on graphics and gameplay continue to rage, so many shots fired seem to come from the endless PlayStation vs. Xbox battle. Is it safe to assume that most PS3 fans tend to favor Battlefield 3 while most 360 fans prefer Call of Duty ? Or is that too big of a judgment?
