Apparently two wizards beat inferno Diablo on solo. If Blizzard does confirm that Inferno was beaten this weekend I expect a nerf incoming for at least wizards and their damage mitigation. They weren't expecting inferno to be beaten for months and likely assumed players would need to farm the necessary gear over that time. I know one of the wizards used an exploit, since patched, to get lots of rares.
I think it's kind of a bummer that the content was beaten so quickly. Based on the offical forums, I don't expect barbs to do it any time soon though.
