Overall from what demos I heard, overall features, and specs, the new Korg PA4X falls somewhere between a Tyros 4 and 5. Has some nice new features, and the black is cool, but a pain with dust and scratches over time.

I'll have to check it out in the store. Like Yamaha and other brands, improvements seem to be in baby steps, and sometimes requiring an owner skipping a new model or two before upgrading. In the case of my Tyros 5, I'm good for a couple more years. I'll have to see if the next Tyros model with be worth the upgrade for me. Was interesting what Korg brought to the table this time around; another real nice TOLT arranger option to contemplate.
