I really like your threads JHawkNH...especially the tables (the power of knowledge overrules all!!).
Anyways, my prediction is that the Wii, depending on supply, should get 50% Markets share by May-June...just in time for Wii Sports Resort.
It would be around April-May, but I believe there will be a small PS3 surge when KZ2 comes out, so there will be delay.
Whether a control of the market will bring more games to the Wii or not is a entirely different subject, but it is an amazing feat to come from third place last gen to be number one this gen.
