I’m gonna guess.
some kind of third party timed exclusive or full exclusive.
Back button attachment and or a pro controller called the “dualsense platinum” would be nice but since it’s 3rd party maybe another deal with Astro or another accessory company for a modular “pro” controller(which was a mistake overall especially the timing of its release and it should have been made by Sony not just licensed)
Either way this is a missed opportunity by Sony that they need to correct immediately
