Why are people predicting massive MGS4 numbers?

I definitely don't think it's crazy to suggest that MGS4 will beat MGS3. Halo 3 it isn't, but I think we coudl see something akin to DMC4/DMC3:

MGS4 is more heavily advertised, bundled with the system, and is one of fewer major games. MGS3 was less well advertised, was not bundled, and was one in a sea of major PS2 exclusives.

Therefore, I think it's possible that despite the lower user base, MGS4 may match or even surpass MGS3, and could hit 5 million sold.

Not saying that's a definite, by any means, just isn't outside the realm of possibility, either.
