Yes the new Korgs are nice ...but everyone is just waiting for the next generation of Yamaha arrangers which should prove to be awesome in many ways!!
New Tyros:
Possible scenario?
Introduced 2018?
Available in limited quantities 2019?
Bugs worked out and in full production 2020?
Priced at $7,000?
If I wanted a new arranger and was debating buying the next Tyros vs. Korg PA 4X; don't think I'd wait around for something new from Yamaha.
