We have been reliably informed (by Ryan Payton of Kojima Productions) in the latest Kojima Productions podcast that Metal Gear Solid 4
and Metal Gear Online
will be playable at Tokyo Game Show. While not necessarily "news" in itself (not for those of you who won't be able to make it to TGS, at least), it means we'll be able to get you some hands on impressions while we're there. It will be interesting to see how the game plays when one of the game's producers isn't handling the controller.
There will also be a new trailer shown which promises to be a bit spoilerific, so those of you who are saving yourselves for the actual game will have to sit out for a few months while those that care less about the game will know more about the story than you do. How hellish that will be.
