They've been advertising it for several months on the EMU site, but I think they're just now bringing it to market. Surely someone will try it soon.
I tend to like the sound of the pianos in their Proteus X line. For their small pianos, they usually just use hard strikes and rely on an lp filter for softer sounds. But the hard strikes they use are well recorded , and only MF or F, so the fundamental has a lot of presence. I'm looking forward to hearing the new piano.
