When V2 is released V3 will be "in the works" (then V4 and so on), so one could keep waiting for ever for the next best thing. If you need to tune your vehicle now, jump in and get it.
It's like buying a computer, new models are released every other week, you have to jump in at some stage. I spent about 4 years "waiting" for the next big thing. Each time I was ready to buy, a newer better model was announced, so I'd wait. Eventually I had to just buy what was available. I'd say I've "upgraded" computers at least 10 times in the last 5 years. No shop has ever cut me an upgrade deal on a new model - let alone given me a free one because a new model was about to be released.
While we'd love to do that sort of a deal, we'd go out of business pretty fast and that would be worse, because then there would be no more updates, ever.
