And where is the problem with missing GPU acceleration? I actually doubt that gamestudio is using it at all, at the moment...
There is no real reason against Linux and Mac support as soon as Android is working. Changing the very few platform dependencies is then only a matter of a few days of work. And in case the new WED is written using Qt, it will probably also just run on most platforms, with minimal additional work.
I don´t believe that there will be linux support, anytime soon, but I also don´t really see a reason against it. Same about iOS btw, if Android works, there isn´t much left to do to make it work on iOS.
