Does it mean that new Italian Grand is PCM and not SGX-2 based as in the Grandstage? And that colour ... would probably irritate me if I look at it for too long. looks like this year will be Yamaha's year, not Korg's.
In the very short intro video it shows the SGX screen while the person plays the Italian grand. All SGX pianos are sample/PCM-based. You can load any of the Kronos SGX pianos into HD-1, though you lose quite a bit in the process.
