theres a chance that its for the UK only or the UK dude made a mistake
"The US side of the company said it wouldn't be. But Nintendo UK insists that the Wii is region-locked. The announcement was made through its spokesperson in response to questions from journalists. Also, in an interview with IGN, Nintendo UK General Manager David Yarnton also confirmed that "games and online services will be region-coded."
In both cases, when the journalists followed up by mentioning that Nintendo US had earlier announced that the Wii would be region-free, both the spokesperson and Yarnton replied that the US side of the house made a mistake. So far, as of this posting, there has been no reply from the US side that has reached our ears or our web browsers, so stand-by for further updates. We ourselves want to know if our Wii would be region-free... or not."
