We have sold through our existing Band 2 inventory and have no plans to release another Band device this year. We remain committed to supporting our Microsoft Band 2 customers through Microsoft Stores and our customer support channels and will continue to invest in the Microsoft Health platform, which is open to all hardware and apps partners across Windows, iOS, and Android devices.
Not only is the Band 2 dropping out of the sales channel, its SDK has also been removed. Reports continue that the team developing the Band has been... well... disbanded. Oddly, the company previously told Foley that it's still "exploring" the wearables market, though what form this exploration will take is, as yet, unclear.
The entire Band project was peculiar. The first Band, released in 2014, was a surprisingly credible first effort at a fitness wearable: Microsoft has a reputation for never nailing the first release of any product (received wisdom being "wait for version 3"), but the Band was a bit better than that. The Band packed in a multitude of sensors and functionality, as well as reasonable software and a range of cloud services. It worked with the iPhone, Android, and Windows Phone.
