The problem is one that's infected most other areas of the entertainment industry as well: big companies aren't interested in anything that would bring them only a modest profit. In this case, if they've already got an English-language localization created for the European release, they could run off 50000-100000 copies with at most a couple of minor tweaks, make a single press release to get the word out, price it slightly higher than the average Wii game to offset the lost economies of scale, and probably still make some money off the portion of the hard-core JRPG crowd that owns a Wii. Thing is, because it would only make them a few hundred thousand rather than millions of $$$, they're not going to bother. (It isn't as though creating a smaller number of units for a less popular game prevents them from putting out the million-plus sellers, y'know?)
