Yamaha US knows nothing about all these rumors (if that's what they are) of any known holdbacks of shipments because of problems. It was news to Yamaha when I spoke with them today. Tyros is on their way here to the US as I type this in. If there is anything that would keep Yamaha from selling these units, Mark Anderson in the PKB department would or will hear about it, but as of today, he has heard nothing but that they are coming.
