Diablo 3 finally beaten on Inferno/Hardcore mode

Blizzard community manager Bashiok has confirmed that Diablo III has been beaten on Hardcore mode by Canadian gamer Kripparrian.
Kripparrian did have some help from a wizard named Krippi, he also mentioned the pair wanted to beat Diablo 3 in Inferno-Hardcore mode before Blizzard applied the recent 1.0.3. patch. The new patch makes the bosses and mobs in Inferno easier so that players can obtain better gear earlier on. Knowing this, they set out to beat the game before the new patch was applied.

Hardcore indeed.
