BD codename was mentioned,for the first time, in 2007 so you couldn't possibly hear it when you were a kid(or maybe you could,are you a kid now ?)
BD on 45nm was scheduled for late 2009 but was canceled. This BD version,done on 32nm and scheduled for Q2 2011,is much improved design based on the first(canceled) version. So a delay is 1.5 years or so,from late 2009 to early 2011. I can't see any DNF theme in BD development,at all.
