Well, make it four things... five... six. OK, we've lost count, but the point is both HD Collections from Konami in 2012 will make their way to the Vita as well. The Metal Gear Solid HD Collection, containing both Metal Gear Solid 2 and Metal Gear Solid 3 will be available on the PlayStation Vita. The Zone of the Enders HD Collection will also be available on the PlayStation Vita.
Maybe because that platform already has a second thumb stick.
