Disney earlier in the year submitted a second generation Magic Band. I can confirm the legitimacy of the photo attached above as this was submitted to the FCC.
I'm actively combing though the FCC data.

While the external photos of the device won’t come out until February of next year (the first magic band saw a six-month embargo as well), other that what has been published in the ID Label document, we can assume at this point that a wristband portion will have a much greater emphasis than being sold separately as an accessory, and the FCC documentation is currently helping to support that.
