Metal Gear Solid: Rising isn't even out yet, but it has already gone Platinum. A trailer for the game purporting to be from tonight's Video Game Awards ceremony leaked onto YouTube today, revealing that the long-awaited game is now being developed by Platinum Games, the studio behind Bayonetta and Vanquish.

　　Metal Gear Rising: Revengeance should be revealed at tonight's VGAs. The trailer--which was pulled from YouTube as the result of a Viacom copyright complaint--shows off a combination of cinematics and gameplay, laying out a story regarding advancements in cybernetics and pitting protagonist Raiden against a similarly cybernetic, sword-swinging foe.

　　The clip bears the tagline "Revenge with a Vengeance," and even suggests the game has also been rebooted as Metal Gear Rising: Revengeance. It also lists the game as being produced by Kojima Productions, which was originally developing it as well. No platforms or release date information was given in the trailer.

　　Metal Gear Solid: Rising was first announced at the 2009 Electronic Entertainment Expo but has been almost completely missing in action since then. Last month, Spike TV executive producer and host Geoff Keighley posted on Twitter that "the truth" about Metal Gear Solid: Rising would be revealed at this year's VGA broadcast.

　　[UPDATE]: In a VGA-closing announcement, Hideo Kojima introduced the trailer (below) for Metal Gear Rising: Revengeance alongside the game's producer, Platinum Games' Atsushi Inaba.
