Here's an idea to solve the problem all the users who've recently bought the Goggles 2 and MC2 and can't use them with the Neo. Why not offer a trade-in: Goggles 2 MC2 combo for the Goggles 3 MC3 combo and some reasonable amount of cash taking into account the upgrade?

djis gonna try to make the most money they can.. its not profitable for them to just take back older products.
