Hmmm, this video about the Aquarium I hadn't seen before (though It's from September) but I watched it and he mentioned he could not access online with his imported version. I hope this doesn't mean it will be region locked again 
I suppose Nintendo could have a way of locking the online for outside Japan until it is released elsewhere, I hope that is the case.
