How much will MGS4 sell by the end of 2008?

[Instant_Karma]

I'm guessing MGS4 will sell between 3.5-4.5 million by the end of 2008. It seems this game will reach a broader audience than the 3 MGSs before it, introducing more styles of gameplay, and let's not forget the robust online component. I definitely see this as the best selling title of the series in the long run. This is counting stand-alone copies, not the bundled copies.
