*sigh*
I am not stating it as fact. However, it is the MUCH more likely outcome. Even you should be able to recognize that. This is not transition from 2D to 3D, it's a transition from 3D to alternative 3D. It's just not as needed.
If you believe even for a moment that this engine right here is the NEAR future ... wrong business for you.
And just for some added perspective, I run my own business now and have worked with major publishers in the past, including a production venture with Electronic Arts on Playstation 2.
Nobody in the industry I have ever spoken with believes polygons are going anywhere for the next 10-20 years at the least. Voxels and the like serve much better as a supplemental feature as opposed to the entire solution.
EDIT: I just want to add that of course I could be wrong, because again I am not trying to state this stuff as fact. I personally believe that the next 10+ years lies in technologies like Tessellation and (unfortunately) 3D displays ...
