Those who are either world travelers or like to buy Japan-only titles through any means necessary will be a little disappointed that Nintendo will most likely be including region-lock software on the Nintendo 3DS.

According to a statement by Nintendo, "there is the possibility that Nintendo 3DS software sold in one region will not function properly when running on Nintendo 3DS hardware sold in another." This doesn't rule out game publishers making their 3DS games region free, so it may depend on the title whether you can play world-wide or not.
