Actually DX11 is more than only tesselation. It can speed rendering up a lot especially in combination with deferred rendering. Many tasks can be put into one single step. This allows almost unlimited lights in a scene and many postprocessings at the same time. There is no doubt that this is the future and that deferred rendering will beat forward rendering on DX11 systems and on the future consoles generation too.
this is all true, but speed upgrades arent a big deal to me. they are expected in an update. bleeding edge features dont always make the cut though and im glad in dx11 they did and apparently work properly as well unlike dx10
