It doesn't offer on-board style creation, so I would have to get an advanced Casio arranger to perform that function. But unforgivably, it also doesn't offer Sync Stop, nor "arranger hold" or "arranger memory." Basically there is no way to make the style pause when you lift your hands off of the keys. This is essential to the way I play.

The MZ-X500 was Casio's first arranger in recent memory to offer sync stop, and it shared much of its OS with the PX-560. If Casio adds sync stop or an "arranger hold" parameter to their NEXT-generation style piano i.e. PX-560 successor, then I would consider it.
