I just spoke with the call center to inquire whether I should pre-order from Wirefly or if they can give me a date. The rep said she saw an official date pop into the system, but was not sure if she was allowed to tell me or not yet. After being on hold while she checked with her manager, she confirmed the 17th as the launch date for all outlets online and in stores.
I apologize if someone else already put this down, but the one constant I have had the entire 2.5 months since CES is that the call center reps know nothing. Seems as official as it can without a press release.
