Microsoft caught our attention on Thursday with a media invitation to a super-secret event in Los Angeles: "This will be a major Microsoft announcement -- you will not want to miss it."

Although the tech giant gave no hints about what it was planning to announce at the Monday event (heck, the invite didn't even say where it would take place!), a source has told the Wrap that Microsoft plans to unveil a tablet to rival Apple's iPad.

The entertainment blog said the company plans to introduce a Microsoft-branded-and-manufactured tablet at the event, "marking a foray into a new hardware category that would put the company in direct competition" with Apple. There's been talk of a Microsoft tablet for years, but nothing has surfaced.

According to the Wrap, the Microsoft tablet will run on Windows RT, a version of Windows 8.

Microsoft's Monday event begins at 3:30 p.m. Media invitees were told that their invitations were non-transferable, "however, if you would like to send your local colleague in your place, please submit that name and it will be reviewed."

The company said additional information, including the specific venue, would be sent to registered attendees on Monday by 10 a.m.
