If you have a brick of unopened V3's, and you are serious about getting rid of them. Sell them for somewhere between 15-20 dollars. Even that low, you are making way over half of you money back, and they will most likely sell. As for V5's coming out. I would not worry about losing deck value off them as I know a lot of people prefer the black and white design. Anyway, if you are willing to sell, I missed my chance to get V3 and I would love to pick up 2 of each color for around 15-20 bucks a deck.
