Predict the Twist of the Next M Night Shyamalan Film

[MetalMilitia]

It wouldn't be a Shyamalan film if it didn't have some retarded twist at the end - so from the following trailer what will it be?

Trailer: http://www.gametrailers.com/player/51238.html

Mine:

- The character in the trailer is in fact not the last "Airbender".
- The name "Airbender" is actually not the queerest thing I've ever heard.
- The last Airbender gets killed by SAW's Jigsaw in a super double twist.
