I'm not sure Wii will ever reach PS2 market share, it does not need to to be honest it will surely have 60% by the time this generation ends, and will outsell PS2's lifetime sales because it's such a phenomena.
Even if at some stage in lets say 2-3 years sales will start slowing down Nintedo can always: Cut the Price (199$ really did push a lot of PS2's , that could happen to wii as well), add colours, start bundling big software or even try some sort of redesign (very Slim Wii ?) or add a hard drive.
