That's a good catch, man. What's kinda funny is, I still remembered what rune it was somehow. lol. Also now that my mind is in that place, I think I see another one on the left side, I'm thinking "Ist" rune, but I'm not sure if that's right.

I, for one, hope it is Diablo 3. I love the Diablo series and I think it'd be a nice followup MMO to WoW. They recently acquired the diablo3.com domain name, so that's a little bit more evidence to that end.
