"Online shops have revealed Metal Gear Solid 4 25th Anniversary Edition."
"Konami declined to comment when contacted by Eurogamer. We suspect this package, released to coincide with the 25th anniversary of the Metal Gear series, includes the Trophy support update that released in August and perhaps the odd extra thrown in."
To be honest, I doubt it will have anything of any substance in it. Probably the same thing that Japan got a little while ago.
