While they will not say when the launch window ends, we suspect that it will slide into next year, which makes the statement a little more believable. The day one title will include Nintendo Land, Super Mario Bros U, ZombiU, Rayman Legends, Call of Duty Black Ops 2, and Mass Effect 3; not a bad line-up if all of the titles actually make it for day one.
Nintendo, as well as a number of third party publishers, say that more Wii U titles will get official launch dates over the next couple of weeks.
