Great post, Diki.
Most of the technology that Yamaha sells in the Tyros line is a few years old as well, but it gets polished, improved, and added to, with each subsequent model.
I think where we'll see more arranger features, is on Roland's stage pianos, although what's on them presently is not really sophisticated. I'm not sure if they can play inversions, for instance.
I'm not sure that Korg is any healthier than Roland, so it may be that they aren't going to replace TOTL arrangers either.
That would be a shame, because then Yamaha would have no reason to strive harder to be competitive...and we Yammie guys will actually lose because of it.
Did you get to play an Audya yet?
