hopefully not,- 1 big plus of flash is still the smal file size (= smal project) and the rapid production time compared to c++, phyton,... I believe that even within a several years from now on this will be a main priority of flash development.

1 big problem imo. is that some 3d- API´s arent that much interested in explaining how they did the tricky parts- they rather want others adopt their classes way of handling their things (meaning: not thinking about it how it works, just use it).

and for the record: the whole 3d stuff is alot easier as most people think here,- it´s just that there arent that much tutorials around (or as good as none) that explain things like UV-mapping, polygon drawing and backface culling/ z- ordering.
