You can't see Europe as one market. They will beat Sony in UK, the by far biggest market here. They will probably beat them in Scandinavia as well. Continental Europe is a tough one. Sony will win here.
Sony spends 45 million Euro per year to be a partner of the UEFA Champions League, the biggest club football (you know, the real football. The one you actually play with your feet ) tournament in the world. And they are promoting Playstation since 1997. The brand recognition is huge. One game is broadcastet live in more than 90 countries. This is a huge deal and being the main-sponsor for 13 years is something. The Champions League Final has almost as much viewers as the Super Bowl.
So I think MS did a great job to be as close as they are. Winning UK, a football-loving area, is awesome.
Imagine not having GamePass on your console...
