Since the introduction of the YAMAHA PSR-OR700 nothing new has come out, I wish Yamaha would pay more attention to that market and introduce a newer model as often or at least close to the TYROS model, they really did a good job on it but it can improve somewhat, wonder if anyone has any clue when a PSR project like this might actually happen? what's the timeline for the PSR's? every 4 years? 5?
