I'll agree with the 88 comment, although there ARE a lot of pianists that just need adequate backing to make a great OMB... It sure hasn't stopped the piano from being good solo entertainment, despite being poor at a controller for other sounds (not to mention that a GOOD pianist is capable of much that can be done on plastic).

But given Yamaha's paranoia at even stretching out into 76 country, an 88 response seems unlikely.

Just remember, a piano player even WITHOUT any backing is capable of holding down some really solid solo gigs. Add a decent arranger with a good piano mode, and who needs a wanky sax solo?
