I think Benny is right. That's the same reason they take JP cars, create a new company to sell them in America (i.e. Honda makes 'Acura'), steal about 100 Horsepower from each model (the agreed upon power 'limit' between car makers in Japan is 270 Horsepower... in the USA, the same 'altered' models rarely tip 200HP) or don't sell the cars at all (Nissan Skyline, anyone?) The USA has higher 'standards' (each person thinks they're the best) so 'sport' cars such as Hondas are sold under the 'luxury' company Acura. The USA has more speed limited roads and a greater focus on road safety; the extra horsepower isn't needed. And alas, the USA is 'family oriented', so who needs a sporty two-seater? Grab a minivan!
Drawn out analogy but the idea is the same. Methikns that Square thinks their 'elite' band of JP players are the only ones that'd be interested, or interested enough to pull a profit. Not only would they have to sell them here, but they'd have to hire a crew to translate everything, publish, buy licenses, etc. for sale first. However, I STILL WANT THEM!
