It'd be hard, the PS2 is a moving target after all. The Wii would probably have to sell about 90M more consoles which would bring its LTD up to 157M over the next few years. It really depends on whether Nintendo keeps the old Wii on the market. They may very well release a more profitable Wii successor and decide that keeping a less profitable Wii on the market is less beneficial than going for a completely new device.
Tease.
