While those % of wii users with the game is correct, it doesn't matter at all because companies care first and foremost about the absolute, i.e. how many it sells. The absolute numbers are what determine their profits and sales.
By contrast, you can use that measure to say almost every PS2 game has failed. Even GTA games would then have an attach rate of little over 10% of PS2 install base compared to SSB on GC with an attach rate of around 20%+.
