Can Metal Gear Solid 4 sell more than halo 3 in first week sales?

[FaRmLaNd]

If the 360 version of GTA 4 couldn't beat halo 3's launch, even though it had a much larger userbase then I really don't see how MGS4 could beat halo 3's launch. It's going to sell very very well but the week one hype for halo 3 was huge.
