Wow, for a second there I thought you meant MGS3 Special Edition (you know, MGS3 SE). I didn't think that they had announced anything like that yet, but I think it's a possiblity that they might, considering that each of the first two MGS games had a sort of special edition follow-up. If you don't need MGS3 soon, I would definitely wait for a few months; you'll probably see a few good deals here and there and an eventual price drop, and they may announce some kind of MGS3: Substance type of thing, which you may want to wait for.
Oh, and just FYI, it's "imminent" and not "emanant." Grammar Nazi strikes again!
