A new report has some more rumors about Microsoft's plan to announce a new Surface PC that may be an all-in-one device. The product could be officially revealed as part of a Microsoft hardware press event that is rumored to happen sometime in late October.

Windows Central previously reported, from our own sources, that Microsoft has been working on a Surface-branded all-in-one PC, and that it has been testing three different display sizes (21-inches, 24-inches and 27-inches). Today, ZDNet's Mary Jo Foley says her sources claim a new Surface-branded product is coming with the code name "Cardinal" and that it "could be positioned as a product that can turn your desk into 'a studio.'"

Microsoft has not yet confirmed plans for a hardware press event in October, but ZDNet says that it may happen the week of October 26 in New York City:

Last I heard, this Fall rollout might feature minor refreshes of some of the company's existing Surface tablets with newer, faster, processors and possibly a couple of other minor feature updates. But brand-new devices like the expected Surface Book 2 and Surface Pro 5 aren't likely to get their big reveals until Spring 2017. Surface Phone, if it does materialize, could be considerably later, sources say.

The event may also show off a number of third-party Windows 10 devices from various OEMs. ZDNet adds that its sources have indicated there won't be any hardware updates for the Surface 3 or Microsoft Band 2 this year.
