don't think so. it will eventually need to sell because of high quality games and even though it has had some this gen, they have had little to do with its sales up to this point.
While high quality games exist on the system Mario Galaxy 2, Smash Brothers Brawl, The Legend of Zelda: Twilight Princess, No More Heroes, Madworld, Okami, Metroid Prime 3, RE4: Wii Edition, they really haven't had that much to do with the Wii selling 50 million copies.
On the other hand, games like Carnival Games, Wii Sports, Mario Kart Wii, Wii Fit, and Wii Play aren't high quality games but have contributed heavily to the faddish success of the Wii up to this point in time. Selling in large numbers but mainly to those that probably aren't interested in sequels and will rapidly move on to other things.
So, the Wii will need many more games like the first group to have a chance at passing the PS2. Much like the DS started out with Nintendogs and Brain Training but now has a very respectable library of games.
