Microsoft has made it clear its move into mobile hardware with the Surface tablet is no one-off, which means by this time next year there's a fair chance we'll have made our acquaintance with the Surface 2.
But aside from a predictable reboot of the two Surface variants that make up the range right now, one forward-gazing mobile prophet reckons Microsoft plans to introduce a third Surface type, one boasting a 14.6in display.
It's called the Surface Book, and according to a series of tweets from MS_Nerd – no stranger to Microsoft-related claims, apparently – it'll come packing Intel's next-generation silicon, the 22nm Haswell chip.
What else do we know about this new-fangled Microsoft creation? Nothing at all. But the size of the display, plus the connotations of the name Surface Book, suggest we may be looking at a device with a more formalised version of the Type Cover keyboard add-on. But that's just a thought at this stage.
MS_Nerd also shares a few nuggets of speculative wisdom on the more conventional Surface 2 devices that follow on from the current models.
The Surface for Windows RT successor is claimed to feature an 8.6in display and will switch from an nVidia Tegra processor to a rival Qualcomm core. The interesting point here is that the current version of Windows RT doesn't appear to support screen sizes smaller than 10.1in, so presumably an update to Windows itself will be coming along too.
The Surface Pro, meanwhile, will be super-sized up to 11.6in, MS_Nerd says, and will drop the Intel Core i5 CPU in the current model in favour of an AMD Temash solution. More good news for Intel, then.
