Feb 24 MWC Update: turns out this is the all-new MateBook 14.
A 2019 successor to the Huawei MateBook X Pro is coming, and it’s looking good — at least in these documents from the U.S. Federal Communications Commission.
The model in question is the KLV-WX9, codename ‘Kelvin’. See the original label document here. Read more about MateBook model codenames here.
At first glance, the updated MateBook X Pro looks very similar to the MateBook 13’s bottom, with a wide air intake for a dual-fan cooling system. However, you can see that this is a more premium laptop: it has a machined aluminum unibody just like the current X Pro, while the MateBook 13’s body is composed of multiple, cheaper, mostly two-dimensional stamped aluminum sheets.
Measuring the body drawing to-scale, the new MateBook appears to be roughly 4mm wider and 7mm taller. So, we may be getting the webcam on the top bezel, or a slightly bigger (14″?) screen, or thicker bezels in exchange for more internal space, or none of the above — Huawei’s drawing may just be distorted.
