Tokila is kinda right-

the only reason for the major difference is Japan. Also, he might not have checked after ioi adjust DMC 360 for NDP.

Wii: 83,000
PS3: 72,000
360: 65,000

You're right about the adjustment...many people forget that NPD showed a pretty major difference with DMC4. PS3 version wasn't far behind the 360 version at all in the US according to NPD.

I believe IN PAL, DMC4 has done better on PS3 than on Xbox360 :

PS3 OTHERs : 320k
Xbox360 OTHERs : 256k

but the brand name dont count when u ALREADY have the console.
Basically, GTA4 will sell better on Xbxo360 just because of the user base.

The question is : do people will buy a Xbox360 to play it ?

DMC4 Comparison:

DMC4 360: 880,000

WW Attach Rate: 5%

Japan - 60,000

America - 570,000

Europe - 250,000 ($10 cheaper, but I think GTAIV will be too)

************************************

DMC4 PS3: 1,010,000

WW Attach Rate: 9.3%

Japan - 290,000

America - 400,000

Europe - 320,000

hmmm... maybe next time some will listen... Wii = 115k

you can tell by the sales of Wii Play and SMG where the HW sales will stand.
