As @vinny mentioned on the Beastcast, a new Attack on Titan game is coming from Koei Tecmo.

It was announced a while ago along with a teaser trailer, but at TGS they've been doing a bunch of stage shows for it.

Here is some off-screen gameplay:

I think it looks really good. They've nailed the aesthetics and designs of the show along with the movement of the 3D Maneuver Gear so it both looks cool and works in the context of the game. The pop-in of the trees is a bit of a shame, especially if they are looking to follow the show and have levels that takes place in a forest, but I suppose they could fix it in time.
