How much would MGS4 sell if released on 360?

[Skeeuk]

shud do ok over a million............definitive version is already out............i think mgs4 will b out on 360 next year.............exclusives only stay exclusives unless its direct 1qst party or moneyhatted dev on 3rd party............ie gaiden2 microsoft moneyhatted it completly so it will never come to ps3............mgs4 is exclusive but exclusivity runs out after 12wmonths at most ie sonata, bioshock etc
