Given the Huawei Mate 20 Pro is still box fresh, we weren't expecting any leaks or rumors about its successor just yet. But a new case patent drops a massive hint about how many cameras it will be carrying.
Spotted by Mobielkopen, the new patent filed by Huawei clearly shows a case that has a much larger hole to accommodate what it likely to be a five camera setup on the back.
Five camera setups aren't unheard of. It's clear that Nokia will be the first with this camera array, with the Nokia 9 PureView, although its setup looks a lot more alien like.
From what we can gather about the Huawei P30 Pro, a phone that's set to come out before its Mate 30 bedfellow, this is a handset that's set to have four cameras on the back - with the cameras positioned vertically.
So it does make sense that Huawei would be looking to fit five cameras on its Mate range, especially given the current square camera setup.
Quite what those cameras will be, we just don't know yet. Unfortunately, it's unlikely that we'll be getting a monochrome lens again as that was dropped on the Mate 20 Pro.
There's been persistent speculation about the use of a time-of-flight (ToF) camera, which allows for better depth sensing, so we do expect to see this within the setup.
Whatever the camera concoction, you'll be waiting a while to see it will battle for the best camera phone accolade - the handset isn't likely to ship until late 2019.
