I think that's big news. I would consider a Kurzweil workstation if they included a lightweight version, but it's mostly far beyond 10 kg.

Actually the Forte is also a workstation, started as a stage piano..

Compared to the forte, the k4 will have double the polyphony, but only 1/4th the memmory and no organ engine...
