I think European delays have a lot to do with localisation issues, remember, there are lots on NON English speaking countries in Europe... text has to be translated, speech changed (requiring foreign voice actors) plus other numerous issues. Remember, a good thing or not, we now come under the big cloak known as the European community (not FULLY... yet anyway!) so when summit is released... Europe is usually last in line, this has been the case with Nintendo, Sega and Microsoft's Xbox... otherwise a PAL label could be slapped on the yank version and hey presto!!!
So really, it's not THAT unusual is it? - Besides, my JAP version is almost here :D still wanna hear more and see more pics of current available downloadable content though!!! I'm as much in the dark as everyone else! :(
