There's a new Jolla Phone in pre-marketing phase right now (almost 9000 phones have been pre-ordered so far). First device deliveries are scheduled for this summer and this should easily be the new benchmark for officially supported SailfishOS devices.

The situation with Sony Xperia devices is not great, the best experience is still on the X10III (from 2021 I think) and there are significant issues with the support of 10 IV and V generation devices (a free beta release is available for those as well).

It seems that recently there has been quite a lot of buzz in the Sailfish community compared to the past few years. In the public repos there are some interesting contributions like xdg-shell support for Lipstick, which looks set to enable compiling many previously unavailable Linux apps natively if that will actually be integrated in an upcoming OS version.
