After seeing this thread I downloaded the demo out of curiosity, and I have to say that I'm really impressed by this, especially for $99.
The main reason is that the playability is remarkably good. The overall responsiveness, snappiness, clarity of attack, evenness of tone, and level of control is as good as any VST I've ever tried - and way better than most. I would even go so far as to day that it equals - if not surpasses - the Modern D in this aspect (though not in others).
In terms of sound, all 3 pianos (German, Italian & Japanese) have attractive and varied tones, and have been very clearly recorded with good presence, although the recordings are definitely not as deep or as polished as Modern D or VSL. It appears that only the Italian Grand has una corda, and I can't tell if it's real or simulated (I suspect the latter) but regardless, it's quite nicely executed, and much better than having nothing at all. Controls and interface are also very clear and useful.
On the downside, there does not appear to be much in the way of sympathetic resonance (like almost none) but a good external reverb can cover up a lot of this, and you can also daisy-chain Pianoteq to work as a sympathetic resonance engine if you have it.
Still, for $99, this is an absolute steal as far as I'm concerned, and the biggest surprise I've come across this year. It just feels refreshingly straightforward, unfussy, and fun to play on, and I have a feeling I will be using this often.
