Let's not have Cross Realm PVP Please. We will never experience Horde vs Alliance from the same server again. I think longer queue times is good. You can do so many things while waiting for a BG and it will make PVP much more interesting since you have to wait for so long to get into a BG.
Edit: I realized, after reading the patch notes, that 2.0.1 was the prepatch to TBC...
