Fuchsia is said to be a re-design of both the Android and Chrome OS from the ground up. Therefore it only seems logical for it to carry support for as many chipsets and platforms as possible.
In this particular case, the Kirin 970 SoC used in the Honor Play smartphone is also one of the first consumer SoC to be supported by the Fuchsia project. On top of that, the reports states that the SoC successfully booted into the Fuchsia OS with minimal problems. The adaptability of the Kirin 970 SoC also serves as an indication that other Huawei and Honor smartphones could be compatible with the Fuchsia OS in the future. Some of the new features expected in Fuchsia includes Vulkan support, architecture that scales according to the device and includes a card-based UI for navigation. It’s important to note that this post is not an indication on how close Fuchsia is to its final release. Nevertheless, it is great to hear about it running on consumer products, and not just on development boards only. (Source: Fuchsia Depository via 9to5Google, AndroidHeadlines, GSMArena)
