The page currently indicates both models as "sold out" even though they haven't yet gone on sale, which indicates that this may be just a placeholder price listing. (A leak from earlier this week pegged the coming device as having a $150 "average retail price" as noted by Windows Central.)
"Captivating sound meets Cortana's intelligence," says the page's tag line.
I had wondered if Microsoft and Harman Kardon might be positioning the coming speaker as more of a business device, given Microsoft's recent partnership with Amazon around Alexa and Cortana. Microsoft and Amazon officials made a point of noting during that announcement that Cortana's specialty is its integration with Microsoft Office apps.
But the page on the Microsoft Store site emphasizes the "home" angle of the device. Cortana allows users to control their music, ask qustions about news and weather, place hands-free Skype calls, control select home-automation devices and also "create reminders and lists, manage your schedule, and more," the page notes.
