UPDATE (November 18th, 2019):
Sony has released an official Android 10 update roadmap for global Xperia variants. It will release the new Android version to Xperia 1 and Xperia 5 users sometime in December i.e. next month. Starting next year, the update will be made available for Xperia 10, Xperia 10 Plus, Xperia XZ2, Xperia XZ2 Compact, Xperia XZ2 Premium, and Xperia XZ3 devices. It has mentioned "early 2020" for the rollout but we will have to wait and see for the actual execution.

This is the time of the year when smartphone brands are busy working on and releasing Android upgrade roadmaps. Sony is yet to offer an official roadmap like OnePlus, LG, Nokia, and Huawei/Honor but thanks to a Japanese carrier NTT DoCoMo, we now have an idea of which Sony Xperia phones will receive Android 10 update.
DoCoMo's list of eligible Sony smartphones is very small and includes only seven models. These are Xperia XZ2, Xperia XZ2 Compact, Xperia XZ2 Premium, Xperia XZ3, Xperia Ace, Xperia 1, and Xperia 5. If you are hearing about the Xperia Ace for the first time, it is because this is a DoCoMo exclusive smartphone and is available only in Japan.
The list basically includes most of the Xperia flagships released in 2018 or later. Some of the noticeable omissions are Xperia 10, Xperia 10 Plus, Xperia XZ1, and Xperia XZ1 Compact. The first two models were released in 2019 itself but it is speculated that Sony did not launch them through DoCoMo. This is likely to be the reason they are missing from the carrier's update list but they should be part of Sony's own Android 10 update roadmap as and when it will be released.
As for the Xperia Z1 series, it was launched in 2017 with Android 8.1 Oreo. It has already been upgraded to Android 9 Pie and was expected to receive one more major upgrade. But a new report from Japanese publication SumahoInfo claims that Android Pie is the final upgrade for the series. If this is indeed true, it is surprising as Android phones are usually expected to receive at least two years of Android updates.
If your particular Sony Xperia phone is a recent model and is missing from the list, we will suggest you wait until Sony reveals its own roadmap. This is especially true for users from outside Japan and for those phones which were not released on DoCoMo. We will keep you updated with any new information that may surface in the future.
