Just weeks after it announced its first-ever Surface-based laptop,Porn movies with a Plot based the (d'oh!) Surface Laptop, Microsoft will host another Surface-related announcement.

The event is scheduled for May 23 in Shanghai, but there's absolutely no details beyond the #surface hashtag in a tweet by Microsoft's Corporate VP of Devices, Panos Panay.

Several of Microsoft's official Twitter accounts posted similar tweets, but with even fewer details. Microsoft's official page for the event just says that May 23, the company will "show the world what's next."

So what's this about? We don't know.

We've seen chatter that the company could launch the Surface Pro 5 (which, according to a recent report, will be a minor (read: boring) refresh, but from what we've heard, this will not be the case.

Instead, Microsoft is more likely to launch the Pro 5 at its Build developer conference next week -- yep, Microsoft's having three major events in one month.

As for the Shanghai event May 23, the location might mean the announcement is somehow related to the Chinese market. And, given Panay's involvement, it's possible that Microsoft will show off some sort of gadget. Perhaps an augmented/mixed reality device is in order, and we definitely wouldn't mind seeing a new version of HoloLens.
