Traditions take a flying leap when it comes to Wii sales. This is remarkably hard to deny when you look at the sales curve on the hardware-from-launch chart, even at small intervals.
At the current production rates, we should see about 40 million Wii systems in circulation by the end of 2008, assuming no production increases (or decreases, assuming demand is somehow met before the 40mil mark; unlikely). That's a good 33% shy of the 60 million estimate, but is also a sort of worst-case scenario. Given that hardware production increases are part and parcel of any console's continued existence (be it revolutionary or just relatively successful), we may well come closer to that 60mil estimate than current sales would suggest. Particularly if the China release of the Wii comes early enough in 2008; China's already shown their interest in the console with the release of the cheap knock-off Vii and Vii 2.
The other guesses, well... Yeah, some of them are pretty silly. Soriku's being the least silly, since the PS3 would probably have done closer that number if not for the various tactics used to get sales up (price drops, discontinuing SKUs and introducing new ones shortly afterwards, etc.).
Sky Render - Sanity is for the weak.
