Will Final Fantasy XIII Be Playable At TGS?

Kotaku writes: "A playable demo for upcoming role-playing-game Final Fantasy XIII has already been released in Japan. Bundled with Final Fantasy VII: Advent Children Complete, it came out earlier this spring.

And with the Japanese PS3 version being something like 90 percent finished, you'd think that the game would be in playable form at this year's Tokyo Game Show. Wouldn't you?"
