New Microsoft Surfaces are set to... well, surface.

Microsoft is hosting a launch event in New York City today at 4pm UK time, and has slated a reveal of an ambiguous Surface product. 

Unsurprisingly, rumours have been circulating on what the release will be. A recent Amazon listing pointed to the possibility of a Surface Mini, with electronics wholesaler VSTN selling smart cover cases for the as-yet-unannounced tablet.

What’s Microsoft got under wraps?

Microsoft could also be gearing up for the launch of a Surface Pro 3 slate. Last week, text on Microsoft’s support page hinted at an undated Surface Pro that might debut sometime this week (and you don’t have to be a math whiz to figure out that the timing of the leak could be alluding to the Surface launch).

The rumoured Surface Pro 3 may get a screen size boost, too, with the current 10.6in model set to be replaced by a 12in tablet. According to IHS Technology analyst Rhoda Alexander, quoted on CNET"There are strong indications that there is a 12in product coming down the pipeline" – CNET also reports that the Pro 3 may use a "power-optimised" Haswell processor instead of an Atom processor.

For those of you who want a minute-by-minute update of the launch, Microsoft will be hosting a live webcast, which you can watch below; the event kicks off at 4pm GMT.
