I think 1M in channel seems a bit low, but still plausible. You people should remember that this title is one of the biggest PS3 exclusives, has high profile and it's available boxed and bundled, which ups the number. This game should also be available in practically every store that sells games, unlike many other games.
So, MGS4 could be undertracked or overtracked, but at this point, i'd take VGC numbers as correct as they can be at this point. Besides, historically VGC has been really close in big titles.
