I am surprised that a third party supplier for the Tyros line would post such a video without explanation.

If it was indicated that it was a wishlist, then obviously a fake. If just labeling it "unofficial", there is always a possibility of a leak, but there was too many errors to draw suspicion.

For so little external changes, maybe Yamaha could get away with special edition Tyros 5 model as they further develop the next TOTL arranger.
