If you consider yourself a soldering gun cowboy, you can get the new Wiinja chip that supposedly will, well, 'chip' your Wii.
Like I said, not interested in playing backups, just want to play imports. This chip doesn't allow for multi-region play, only plays backups. I modded my xbox a few years back, but I don't really want to do that again, just want some kind of disc loader solution. Quick and easy.
Never saw the point in modding the GC when there were really only a couple first party games each year.
I think the Wii is going to do really well in Japan, unlike the GC. There will likely be a lot of interesting games that we won't get here, regardless of how popular the Wii becomes in the U.S.
