Unconfirmed: Borderlands 2 In Development

Randy Pitchford dismissed any and all rumors of Borderlands 2 being in development just last month. However, he now mentions it again at the end of a Duke Nukem interview.
I'm sure Duke will have some demands of me and I've gotta work on Borderlands 2, right? (laughs)
The remark is being reported all over the place as "confirmation" but by the tone it looks like he was just making a joke to end an interview. If so, I guess we'll have another denial soon enough.

Addendum: indeed, VG247 clarifies it was a joke and should not be interpreted as confirmation.
