Hey doc, let me turn your question around-where do you see ProVari's in a few years? Are they going to evolve as well, or are they like, "This is it-it works, it sells, why mess with it?" I have a mini LT, and I think it's great, but I see a lot of room to grow as well; brings to mind the Ford Mustang vs. the Chevy Camaro; the Mustang is a success because it evolved and changed with the times while the designers listened to what the buyers wanted too; meanwhile Chevy tended to produce the same design of the Camaro (great car, don't get me wrong) year after year until they realized they were behind then had to scramble to play catch up in great, risky leaps.
Of course they will, but I feel the LT PV's evolved more out of necessity due to flaws in the original design that weren't foreseen whereas the Provari was originally more strenuously tested on low resistance before it was released, hence its original amp limit.
Also, Chinese manufacturing tends to hit the ground running rather quickly. It's only been a few months since Volcano sold the first American-retailed Lavatubes and there have been many models produced since then. It would be a lot more money and cost for Provape to continuously produce new models based on consumer input, so I don't see their evolution running quite as quickly unless every upgrade is just the circuitry just like the V2.
