Enter Layle, the person who has been all over the trailers and art for the game (and in the image above this very post!). As a Crystal Bearer of the Clavat race, he has some unique abilities that allow him to manipulate gravity (not everyone forgot magic, we suppose). The story of the game revolves around him and his run-in with one of the supposedly extinct Yukes.
We won't go into the story any more than that in case you're trying to remain pure, but know that the game plans to use the Wiimote in some interesting ways. Since Layle can manipulate gravity, he can do a variety of different things to the environment around him and the objects in it. He can grab demons and toss them at other demons, kind of like a basic attack (though the Famitsu article says Layle will have different options depending on the demon he grabs). If he tries to grab something heavy or stationary (the example given is a ceiling lamp), then it will send him flying toward that object like he's using a grappling hook.
If you want to read IGN's summary of the Famitsu piece, then go ahead and give this a click. For those of you that want to look at the pictures, a scan has found its way online here. Oh, and in case you were wondering why it's taken so long to get details on the game, know that it's due to Square Enix not even having started development on it when it announced the title. Smooth move, Square Enix!
