I purchased a V2 in December. This was before the announcement of the new UV process, but I think the keycaps were made with the UV process, because they are SO much nicer than the laser-etched ones I had purchased a few months prior. I'm very pleased with the quality, feel, and finish on the new keys(*).
They have a PBT-like surface - the same "rough yet slippery" character of PBT - but less pronounced in both regards. I've been using them for over a month now, and they don't show any indication of wear or shine.
(*) One thing to note is that my new caps are black, while the older laser-etched ones are blue and gray. So there may be additional differences in terms of material, thickness, etc, and this may not be a fair comparison.
