Feb 6th, being a Thursday, makes sense.
IMO ... Verizon is trying to cut a better deal with Nokia's potential new owner, Microsoft. That merger has not happened yet, and that is what has delayed this phone for months. Since it is branded Verizon, they need to sell these before the new Nokia's are announced at MWC, which is at the end of February. This would also explain the lack of promotion on the 929. ... Verizon does not want to spend a lot on PR, to have customers mad, the phone they just bought, is 'last years' model. Your average customer will not know ... and techies will know to wait until MWC before buying.
(I have waited months for the 929. What is another couple weeks? If nothing is announced at MWC [which I doubt] ... I will buy a 929 Off-Contract from the MS store)
