Comparing the numbers of units sold since launch puts the Wii in a very strong position, but look at the PS3 it isn't doing as badly as we all probably thought. The PS3 might have a dismal selection of games, but it is still giving the 360 a run for it's money.
So if the Wii is doing so well, how does it compare to the current king of all console wars the PS2, which has currently sold more than 120 million units:
The Wii does more than double the sales of the PS2 in the same period from launch. And as there is no sign that demand is going to lessen anytime soon it isn't unreasonable to predict that the Wii will sell more than 240 million units in five years.
However as Nintendo has been so successful in releasing second iterations of the GameBoy Advance and GameBoy DS everybody is expecting them to do the same with the Wii. Could we see everybody who has already bought a Wii buy a second one or people like myself who haven't yet bought one yet be swayed if Nintendo iterates on it's design!?
Clearly by the kinds of numbers we are seeing in this generation the market is easily large enough to sustain multiple console manufacturers.
