Many expect New Super Mario Bros U, shown at E3 2012, to be a launch title for the Wii U when it hits stores this holiday season. It seems though from some footage released from IGN that Nintendo PR Manager Kit Ellis is heard saying the anticipated title will be available after the Wii U’s launch.
“So that’s a look at New Super Mario Bros U, coming out for Wii U not too long after launch.”
- Nintendo PR Manager Kit Ellis
From my understanding everything Nintendo had shown at E3 is aiming to release this year. Pretty sure that is what Nintendo said anyway.
