Microsoft's upcoming Spring hardware is close, but if you have been holding your breath for the Surface Book 2 announcement, then you'll be sorry to hear that the company has no such plans. Not only that, but some reports mention that it is also unlikely that we'll see the Surface Pro 5.
The same report does say that the Surface Book 2 does exist, but it is just not ready yet. This means that the notebook is expected to launch alongside the Surface Pro 5 later in the year. Probably one of the main reasons why the laptop isn't ready is because Microsoft ditched the 2-in-1 design and is working on a traditional design without a detachable keyboard and touchscreen support.
