Nintendo of America has confirmed that the Wii will be region locked for both first and third party games. Nintendo issued a statement saying “Wii will be region locked by territory”.

The whole issue started when Nintendo’s genius Perrin Kaplan made up the fact that the Wii will be region free, and then a Nintendo UK representative said Kaplan was wrong. At least now it’s official; you shouldn’t pre-order your Wii (or games) from other territories.
At least we know.
