Nintendo sees Wii sales leveling off

Nintendo (NTDOY) said sales will level off in the next 12 months as fewer game fans run out and buy Wii and DS game consoles.

It has been almost three years since the surprisingly popular Wii started selling faster than Nintendo could produce them and nearly five years since the original Nintendo DS handheld game player was unleashed.

Nintendo recently released the Nintendo DSi, adding a camera and wireless capabilities to the dual-screen game player. Can a new Wii be far behind? How else can Nintendo revive sales?
