I think ZombieU will be the Red Steel of the Wii launch titles. An original game that is of average to above average quality, that is bought up by the masses for a unique Wii U launch experience. It will make alot of money for Ubisoft and a sequel will be eventually made. However, unlike Red Steel, I don't see the sequel of ZombieU being nearly as cool as the sequel to Red Steel was.
Nintendo Land will try to be the new Wii Sports, but I don't think it will work. Wii Sports was amazing because it was the first game you moved to play a game and sports are the perfect games to represent the power of movement. Nintendo Land doesn't have that immediate connection so it won't have the same impact.
