Sony seems to be headed towards prioritizing US and Asia over EU (relative to demand). Time will tell if they're making the right decision or are taking Europe for granted. But I don't think it will matter because once demand in US and Asia is met, they'll start sending more units to EU, so things should normalize in the short term either way.
Then again it would not shock me that even with significant production improvement, PS5 will still fail to meet demand in most regions until mid 2024. I think Spider-Man 2, PS5 revision, and potentially PSVR2 might help increase demand greatly. The revision in paricular may be a game changer because it could be the moment Sony finally pushes towards digital edition adoption ($100 cheaper).
