Wii has already had its bigger system sellers: really with two Wii Fit, two Wii Sports, a 2d Mario, 2 3d Mario and possibly every kind of casual or Nintendo game already out what could Nintendo do? Nothing, they should just start milking the users before it's too late: a redesign with bundles, a Players Choice and new colors should move the Wii into a safe territory...But the Wii is declining and will never return to 2008, not without third party support, without the games that many people want and won't find on Wii.
Its the sharpest decline ever I think, but that happens because this is a completely different gen, with a new market and with Nintendo on top again. Wii is selling like PS2 after 4 years, but considering in 2008 and the most of 2009 it was way better next year will sell probably worse and will just go down and down.
Again, Nintendo can't do anything now other then buying exclusives or trying to convince third parties to port big projects on Wii.
CURRENTLY PLAYING: Xenoblade (Wii), Super mario 3D land (3DS), Guild Wars (PC)
