Hmm... How'd I get that around America?
NOA said that for their market, releasing the XL is the more logical choice. Producing units of the regular N3DS would mean they would be losing money. In Japan, the N3DSXL has been selling three times as much as the regular version. That gap might have somewhat less, the same, or higher in North American territories.
As for why it is coming out in Europe, I think that may have to do with Oceania and Europe sharing the same region. NAL released the N3DS in Oceania before solid sales figures could be taken from Japan. Europeans are already importing systems from there, and it'd skew their sales figures even further if they continued. NAL would have a crapload of N3DS systems sold, while NOE shows that N3DSXL sales are subpar. Game sales wouldn't be affected by this, as Australian 3DS systems can run European games and vice versa.
The money goes to the same company, but we know that Nintendo uses sales figures to figure out what the consumers want. They also do this with Club Nintendo (and probably the upcoming replacement). That might change their plans for a next system, or even their plans on what to sell where.
Of course, I'm just theorizing there.
And of course, there's nothing to stop Americans from importing a regular N3DS from Europe. However, it would get very expensive if they wanted a decent library of games. None of their NA copies would work on the new system, and all the N3DS-exclusive/-enhanced titles, they would have to import from Europe. It all adds up to be a huge investment for those people, and I doubt many would actually go through with it if they thought about it logically.
