Take the 360 out of the equation for a minute...
Everybody who buys popular games that owns a PS3 will get MW2.
Everyone I know who has a PS3 will get MW2. (seriously.. this is a first)
With that said;
3.1 mil 360
2.4 mil PS3
Total First Week; 5.5 million
WW difference; ~700,000

X360:

Total: 3.520M


PS3:

NA: 1.2 Million

Others: 1 Million

Total: 2.250M


Altogether: 5.70M

it going to be a monster 5.4 mil i recon,
360 = 3mil

I would guess about 5-6 million combined on both consoles worldwide.
