Your Wii will definitely be a D2C... assuming you buy it new.
There is currently one chip out that supports the D2C.. but it's one hell of an install. 30 wire install, extremely tiny points, etc... I believe it's called the "D2CKey"
I know there's another in the making that supports D2C, it might even be shipping... I believe it's called "Infectus" or created by "Team Infectus" or something with infectus. lol. This one has a 13 wire install.. but some extremely small points as well.
