Update: Bashiok has confirmed this IS the first hardcore inferno clear. A HUGE congratulations to Kripparrian and Krippi on meeting their goal prior to the 1.0.3 patch!
The first streamed hardcore inferno clear happened today at 1:44 am PDT by Kripparrian and Krippi. Whether or not this was the world first clear is unclear. Bashiok commented on his Twitter account regarding the subject.
When asked why no other hardcore inferno clears have been made known, Bashiok tweeted the following responses.
Well you have the data, why don't you tell us if someone had already killed d inferno hardcore then?
We don't publicly announce/recognize world firsts. I'm just surprised that was the first one that was publicized.
Could you at least give a date on the actual inferno HC first clean? Or how many people did it at this date?
I'll double check it when I get into work tomorrow. :)
Regardless of whether or not this was the world first, it is still very impressive. Congratulations to Kripparrian and Krippi!
