Just to put things into their (hilarious) perspective.
The PS3 would need to sell at it's current level (with the higher sales during christmas balancing out the fact that all console's sales decline after a point) for 457 more weeks (8.79 years)
The Wii would need to sell at it's current level (with the higher sales during christmas balancing out the fact that all console's sales decline after a point) for 125 more weeks (2.4 years)
