You took an old ass screenshot, and compared it to cataclysm beta content, which btw, doesn't look like that on live. The water in that screenshot is the only thing decent, and that water isn't even on live. They scrapped that water and put in a lower quality one.
It looks nothing like like The Clone Wars
Now lets compare that to CHARACTER models.
that is the BEST possible comparison. The older models in WoW are completely outdated
Just look at the armor in that WoW screenshot and compare it to the armor in the SWTOR screenshots. The armor is completely 2d looking and the textures are completely flat and on the same layer as everything else when it shouldn't be.
The poly count is MUCH higher than of WoW, and saying otherwise would be just kidding yourself.
