Microsoft today sent out invitations for its previously rumored hardware event. It will take place in New York on October 6.

What hardware will we see? The company tells us that it's for first-party Windows 10 devices, but beyond that, isn't providing specifics. It's believed that Microsoft will launch both the Surface Pro 4 and a pair of flagship Windows Phone devices, codenamed Cityman and Talkman. There's also talk of a Band 2 fitness device, though technically, this is very unlikely to be running Windows 10 in any of its many incarnations.

While credible specs for the phones have leaked, both the Surface Pro 4 and the Band 2 are big unknowns. A Skylake processor is, at this point, an inevitability, and the basic form factor isn't going to change—Microsoft has said that Surface Pro 3 accessories will remain compatible with future devices—but beyond that, it's an unknown.

Likewise, the updated Band is, like its predecessor, a complete mystery. The first Band caught the world off guard—there were rumors of a Microsoft wearable, but it wasn't even known if it would be a watch, a fitness band, or something else entirely—and it looks like the secrecy that surrounded that device has been retained for its second iteration.

Whatever Microsoft announces, we'll be on the scene to tell you all about it. It'll kick off at 10 AM Eastern.
