Has it been confirmed that the VC games are also region locked? I haven't seen anything that says either way. Then again, the fact that there are different games available in different territories probably means that it is.
How would Nintendo enforce regions anyway? I suppose it could be like iTunes where you need a CC or point card, etc from the specific country to buy. If that's the case, then it'll probably be easy to buy a point card from an import dealer.
Hopefully people will be able to buy from any region w/o needing some kind of modchip/hardware mod.
