Interesting video, but still just a lot of speculation, at least as far as the lower-cost Yamaha keyboards. It was already posted here that Yamaha is introducing a "family friendly" keyboard this year, and the video provided no additional details on it. And while I agree that there is a large gap in Yamaha's PSR line-up, it isn't as large as the gap from the PSR-E463 to the PSR-EX700 as he is saying. There is still the 76-key PSR-EW410 in there, and while the PSR-S670 is now an older model, it is still a current model. The jump from the $400 PSR-EW410 to the $800 PSR-S670 is still pretty big, but not $1100.
