You just can't rely on manufacturers to make up for this with clock speeds and architecture.
Quad core optimization has taken a lot longer than dual core did (we still aren't there).
Adding more cores doesn't help legacy software such as WoW, the only thing that can improve that is clock speeds and architecture.
There will come a day when a quad core cpu is isn't enough like many dual core cpus seem to be in some titles, however that day isn't today.
You can't abandon one to improve the other, and I think AMD did exactly that with Bulldozer. Intel on the other hand simply improved core performance this time around, they didn't add more cores. I guess we'll see which of our two stances pans out in about a month.
