The more Pa4X boards people buy, the more used Pa4X boards are going to be traded and resold to upgrade to the new Tyros/Genos model.

Just look at the trends here in the General Arranger forums, a large percentage of players always trade to the latest new model, regardless of brand, only to resale again shortly after being bored once again or not up to expectations.

Learn your instrument and features, and make the best of your latest arranger. I have learned the Yamaha O.S. quite well, and will stick to what works for me, plus compatibility of previous work.

The Tyros 4 was a beauty, but I couldn't resist the new Tyros 5 features, namely Organ World, Ensemble, and the upgraded voices/audio styles. Obviously, one has to upgrade from time to time, but important to consider wear and tear, reliability over time, and best interval to maximize trade in value.

If you already have a board, I would wait and see what Yamaha offers in their upcoming Tyros/Genos model, but I have to agree potentially a year or so is quite long to wait.
