I really don't think the V-3 is going to be better than the cubes that are on the market now. V-cubes tend to be very stable, and they do cut corners well, but so do all of the main types of 3x3s - I think that, if made, it will become just another one of the types of 3x3s that are common for people to use. As for V-2 and V-4, well, they could be very good, but Verdes will have to fix the problems that caused the 6x6 to click and have mechanism lockups. Otherwise, the 2x2s and 4x4s that are already on the market will be noticeably superior.
