Microsoft has sent invitations to a Microsoft Surface event on 20 May in New York City, with the following description: "Join us for a small gathering."

Rumours have long claimed that Microsoft wants to introduce a mini Surface tablet. Microsoft itself has even admitted it is working on "multiple aspect ratios and sizes" for the Surface tablet range, though it has never officially announced when consumers could expect to see those new Surfaces. Today however Microsoft may have given its first clue.

It's not definite that Microsoft will unveil a mini Surface later this month, but the most recent reports have said the new tablet is expected to arrive in 2014. That said, the mini Surface will allegedly feature a 7.5-inch 1440x1080-pixel resolution display with a 4:3 aspect ratio. It'll also boast a Qualcomm processor and possibly Windows RT. If true, the tablet will be a lot like Apple's iPad, in terms of size, and  it won't support legacy programs.

And that's it for now. Pocket-lint has of course contacted Microsoft for a comment, but we likely won't hear anything concrete until the Big Apple event.
