In other cases it may be a case of marketing, some companies want to see how good their game is before it's released worldwide so they release in one area first, see how it goes, then branch it outwards if it does well. I think that's what Zen United were doing with Blazblue, testing to see if US and EU still liked classic sprite-based fighting games, and because it sold well they sent out a sequal and Arcana Heart 3 as well. Can only hope Cave have the same idea and release Deathsmiles 2 here, I loved the first one...
In a sense that's also what FFXI did as well, released in japan first, where it had a few problems, so they fixed those problems before giving it a release for US and EU.
