Dragon Quest X will have a presence at Tokyo Game Show next week. Square Enix updated the game's official site today with notice that a video will be shown at the event.
The unveiling event from this past Monday already had a lengthy trailer and plenty of gameplay footage. It's likely that the TGS footage will be the same. However, the fact that Square Enix is promoting the game at the event suggests that we may get additional news as well, including details on the promised beta test.
