Donny probably thinks everyone buys every subsequent model as soon as they come out. Truth is, probably a LOT more than he thinks wait at least TWO generations before purchasing and trading up... It seems to take at LEAST that before any model can be considered more than a simple upgrade from the previous. I can't remember the last time ANY keyboard manufacturer released two revolutionary leaps forward in a row.

They usually leverage the technology of the first 'revolution' for another model at the very least, usually two. THEN come out with another 'great leap forward' six to ten years after the first. My bet would be, the next TOTL Yamaha arranger NOT called 'Tyros' will be the first thing of any significant departure from where we are now...
