If so, it's probably an anti-piracy thing. Nintendo is far to commercially inclined to do this for fun.

If anything it will just encourage piracy.  If people are forced to wait 6 months for a later region release and cannot import many will turn to piracy instead.

This "encouraging piracy" thing doesn't work anymore. With or withour region locked people are already looking for ways to allow piracy on it.
That chinese dude that stole that 3DS was already getting request for that purpose lol.
