Hi,
I saw in a previous post on this subreddit that the 2015 models are getting updated to Oreo.
Considering that the XD93 were the high end models in 2017, I was expecting that they would also grt updated to Oreo (forget pie) but I haven't received any update. The cheaper models from 2017 already seem to have Oreo.
Has Sony abandoned the models that people shelled out nearly 2000 euros for?
I think you'll have to check on your model's support website, Sony posts the firmware files there along with the OTA, maybe your model already has an update.
