Well, we won’t know anything until they post the specific requirements for the game.
I checked the World of Warcraft forums and there are no official specs for it. As long as it doesn’t require hardware T&L there is a good chance it might run on the TR although with a lot of the graphic goodies turned off.
I have read that a 64MB video card might be required. If that’s the case then there’s a chance that it might not run. I know that the Intel Extreme Graphics 2 can use up to 64MB of memory for video but it might be pushing it. We’ll see what happens when this product actually ships.
