@DirtyP: SSBB was a bad example because it was stretegically released (in every region) at a time when there were nothing big coming for PS360, to get that audience jump to Wii. So the release schedule is easy to understand.
Anyway, you still have a point there. But the main reason for all the delays is "tricky" european market, with a large number of different languages, different cultures, different importers and different taxing. The required amount of work is so big for the european release, but admittedly, EU have helped a lot in this case.
There are some exceptions, like SMG, MKWii and Wii Fit (although it took really long for Wii Fit to get released here after its initial release).
