Microsoft is hosting an event on 20 May in New York where a new Surface tablet is expected to appear. Until now it was a Surface Mini touted to make the news, but it looks like a new Surface Pro 3 may be there too.

A mention of a "Surface Pro 3" has appeared on a Windows 8.1 support page and was captured by Neowin before being removed. The text read: "adds support to the Surface Pro 3 camera". A Microsoft employee has since claimed this was a typo.

Previous rumours have suggested the event would be host to a Surface Mini unveiling based on the invite wording: "Join us for a small gathering". Other rumours have supported this suggesting a 7.5-inch 1440x1080 resolution tablet running a Qualcomm processor, 4G connected and powered by Windows RT.

This latest leak seems to point towards either an extra tablet or a different name for this new smaller tablet. Although it's most likely the Surface Pro 3 will be as the name suggests, a follow-up to the Surface Pro 2.

Previous rumours of a Surface 3 have pointed to an Nvidia 64-bit Tegra K1 processor dubbed Denver. The source that leaked that detail also claimed there would be size variations.

While it's all very much at the rumour stage it looks like Microsoft may unveil a Surface Pro 3 and Surface Mini at its New York event on 20 May. Expect live coverage from Pocket-lint.
