My post wasn't clear, I'm happy to pay for and I think you have to charge for a OpenGL 4 renderer, I also think most people are.
Its more a a clarity on price, if its $200 for kickstarting linux/windows/mac which I understand is 3.1, how much for a current user to do the same. If its $200 its means they will have paid double.
i know we have LE3 now so get to use in advance, Some current people might be happy to pay upfront.
Also what about adding European postage for the t-shirts
I need to add to my collection.
