No one knows what will happen in the distant future as it's up to market forces, but I'm confident that VS and GS will still be around in 4 years. If SPUs are mostly used to build data structures that doesn't obsolete VS and GS as today VS and GS are not used to build data structures.

okay i have made a mistake that VS builds data strucutures, but as far as i understand, GS does. They build primitives like triangles by grouping vertices, so in other words, they do build them. I am not an exoert, but i would appreciate any corrections.

Thanks

The GS outputs a few primitives in a strip or list format. I believe the presenter was thinking of something a bit more complicated when he mentioned data structures. Programmable graphics would seem to require the ability to generate things like octrees, kd-trees, bounding volume hierarchies, etc. Someone might be able to make a current GPU generate some of these more complicated data structures, but it certainly wouldn't be efficient.
