DS420/920+ is their latest releases. Plus series models are usually on a 2-year cycle. I would not expect new models until 2022.Upgrading from 218play to a plus series models will increase the performance significantly. You would get a Celeron multi-core processor with a graphics chip built-in as well as multi LAN and cache options. You will also unlock an option to install apps you were not allowed before.DS920+ can be also expanded. Synology do not replace these expansions very often. Because these are brainless boxes anyway. There is not much to improve. All the hard work is done by a NAS itself.I hope this helps.
