Rumor: 3DS is region locked.

For me this isn't a problem if all  major games I want are released in Europe.

I recently imported an NTSC PSX to play the likes of Xenogears, Chrono Cross and Valkyrie Profile.  It isn't cheap at all and I would far prefer not to replicate it will the 3DS in a decade or so.
