I wondered about this for awhile, since I live in the US. But from the sounds of it, it sounds like a mixture of preference and history. I've read and hear Nintendo didn't treat EU very well during their strong years, ignoring that base, only providing a few major areas in EU, and having a few language options available.
But then Sony came over and had a full simultaneous release in the EU, having almost all languages covered, having some fine enough games, and getting their 1st main title Final Fantasy game, 7 (Mystic Quest does not count ; ) ) I'm not sure if this is accurate as I'm overly simplifying what I have heard and read, but that's what I got.
Since then, there has been no need for anything else. Sounds like EU is fine with Sony alone.
Dance my pretties!
