I'm looking forward to the next real Metal Gear Solid videogame since last year.
Konami now released a video with 11 minutes of "Metal Gear Solid - Ground Zeroes" gameplay. I could not believe that this was actual gameplay footage until the cutscene changed without any transition to the well-known third-person perspective the player is controlling Snake from.
The game is currently under development for PS3 and Xbox360 but could also be released for next-generation consoles such as PS4 and the next Xbox.
EDIT: Hideo Kojima presented an awesome new trailer at GDC 2013.
