Xperia 1 IV, 5 IV and 10 IV support

[SamFisher]

The 10 IV and the 10 V have the same SoC (different than the 10 III). Hence my suggestion to first focus on a port for the 10 V, and then back-port it to 10 IV (for those few people who bought it in hope that it’d support SFOS), which should be quite easy given that they share the same chipset and mostly the same hardware in general. But doing it the other way around, i.e. first supporting the 10 IV and only then (possibly) the 10 V, would mean that they follow exactly the same scenario as before, i.e. always start supporting a model that is just being replaced by Sony with a new one, and hence its availability diminishes at sight.

No, they would because that would delay Jolla another year. Xperia 10 IV is out there already with several bug fixes so the most likely scenario is that they are already working on a Xperia 10 IV port. Also when they deploy Sailfish for a device they want the kernel to be as stable as possible and not too early for a particular model.
