As an EU gamer I co-op/multi with gamers from France, Germany, Spain, Italy, and recently when we're in lobbies they're all trying to secure PS5 pre orders. Ebay in their countries have the same scalpers situation. Germany seems the most hit by shortages.
Both the series X and PS5 will sell out but from what I'm hearing and seeing anecdotally, at least here in Europe, the PS5 demand is at a different level entirely. And unfortunately, I think scalpers are going to make a killing this November.
