I contacted Yamaha about a week ago and they couldn't tell me anything about the keyboard. Maybe they have more info now.
The thing is, with my PSR 740, I have access during a performance to as many styles as I can fit on a floppy. Sure, it takes a few seconds to load the styles, but it gives me time to talk to my audience. If with the PSR 2000, I only have convenient access to 20 user styles during a performance, from a performance standpoint, I have no reason to upgrade from the PSR 740? The whole reason I've been waiting for months for this new keyboard to come out is that I've been hoping I'll have access to more user styles during a performance, not less!
I'll try contacting Yamaha on Monday, and hopefully, they will have a way of conveniently loading styles when the flash is full.
