Donny,

There are going to be a lot of incremental choices in the future.

Most of the R&D for Yamaha has already been done on arrangers going back years...they just haven't built a Tyros the size and capability of a PA 4X.

So far, Yamaha has been able to make $$$ on pretty small changes. Yamaha arrangers actually made a bigger change(IMHO) from the PSR S950 to S970 than they did from Tyros 4 to Tyros 5.

IMHO...the next big thing in arrangers has been the Korg PA 4X....question in my mind is whether or not Yamaha will follow the lead that Korg has set.

Biggest problem Korg has is that Korg arranger users haven't started fixing their own software problems like Windows users have done for years...maybe they can't???
