I'm not entirely convinced either way. On one hand, there's the screenshot EvilMonkey pointed out with the weird color block around Jazz. But on the other hand, it wouldn't be impossible to create some of the things seen in those screenshots (assuming the animations aren't more complex than I think they are). Of course it would be easier to believe if Dx said the levels would be TSF, but he could've also tried going above the animation limit of 1.23 (I still have to test the effects of this myself, and I wouldn't recommend going over the limit without extensive testing). But that's all just speculation.
