I bought it, too, for like twenty bucks or something. I had some fun playing with it, and even worked it into a song - once. Since then it's just been taking up disk space here, too.
From the video it seems to me that VS-2 sounds exactly like VS-1, but with a chorus. Not believable as an acoustic emulation, not rich enough to serve as synthesizer. Looking at their website, it does indeed seem to be the same instrument under the hood, but with new presets, new effects, and UI improvements.
