Can anyone believe MGS Peace Walker as MGS 5, instead of Rising?

[Simulacrum]

I just can't think of it more than Metal Gear Solid Portable ops 2.Even tho Portable Ops was great from story point, gameplay was pretty sad and dull when you think about it.

And expecially now that Mgs 4 have been released, while playing Peace walker demo I feel going back 10 years to Mgs 1 gameplay.

And Co-op?Not with PSP, not with Mgs.
