According to Xperia blog, the update should also be rolling out to the Xperia X Performance very soon.

This is great for users of the phones, as they actually get to have the update before the year even ends. Android Oreo treats them to a bunch of new features such as beefed up security, better system resource management, better storage optimization, and an improved multitasking experience.
This rollout knocks off three devices off the official list of Xperia devices receiving the update, which was released by Sony last August.
