Dissidia Final Fantasy

I stumbled upon this video yesterday, I was shocked that they were actually doing something like this. Especially seeing how they already have Kingdom Hearts where the crossovers are done. But now this game seems to be crossovers of only Final Fantasy leaving out any Disney characters. From the pictures I looked up it seems to be the old Final Fantasy Characters up to 10. I didn't see any XI, XII, or XIII characters, but they did have Ultimicia which I think is really cool. She is one of my most favorite villains in the Final Fantasy series.

Not much is known about it only that it's for the PSP. I can say that it looks like something I am willing to play when it comes out.
