Perhaps it's a question for another topic, but either way isn't the point kind of "moot" or whatever?
If it's region-free, hooray. I'm assuming you guys expect to import some games.
If it's region-locked, I'm sure that with the Wii being as popular as it is (or rather, as popular as it sounds like it likely will be) that soon enough someone will find a way to bypass such protection via mod chips or otherwise. If you don't mind voiding your warranty or whatever, that is.
The last time I played import games was in the last days of the Super NES. That was an easy fix - just taking the pliers and snapping off the tabs in the cartridge slot. If only they were still that easy.
