not on PS3....its not made me happy with what its sold so far.

I feel it should be past 4.5 million right now on PS3

Two million worldwide week 1 possible?

I was defending that number in this thread, but it seems no one agrees with me so far.

@NJ5

as I said I may be surprised with the overall first week sales...but I don't want to disappointed either

 Possible, but not likely. If Europe was as front loaded as NA then I would say more than likely. 

Japan - 350k

NA - 750K

Europe - 700k

Total - 1.8M

I think that is best case scenario. Close to 2M but not quite, in my opinion. Europe will have better legs than NA, so MGS4 Europe > MGS4 NA.

I don't want to get too excited for this game's sales.

I'm intentionally low-balling it, so that I can be super surprised next monday, tuesday, and wednesday (Sales come in).

i guess it will do much worser than everybody expects.

japan 200k
nA 500 k
europe 350 k

first week

 Already 210k pre-orders in Japan

for the record

MGS3 did better in EU..so y people are putting MGs4 higher in NA I do not know
