From what I've read though, the new audio styles will ONLY come from Yamaha, and will be released on their schedule...

Take a look at how few new styles Yamaha release right now that don't even NEED the audio style feature (which adds considerably to the complexity of producing them), and this new feature seems to be meeting my expectations. Yamaha once again go the proprietary route, and dole out new content in dribs and drabs.

408 styles, and only 25 that even USE their new feature? I am afraid I am unimpressed.
