Looking at the video reviews and thought process behind this synth ('lanes' inspired by early serialist composers), the Wavestate looks like an absolutely brilliant synth.
For sound design, electronic music, as well as garden parties, new age spa music
Ozric Tentacles used lots of Wavestation and it can sound really amazing in the right hands.
Buttttt......... it is (so far) another wavetable synth where you cannot load user samples, even though it has a massive library of sample data on board. That makes me wonder, is there something special about those samples and how they interact with the synth engine, or they need to be a max length or whatever. Even if that were the case, sonically breaking things is fun, and a sample upload dialog could reject any samples that would crash the OS.
I'm really curious to know if uploading samples might be included in a future update, and if not, what is the thinking behind that decision. I'm sure many people (including me), especially sound designers, would make a decision to buy based on that feature!
