Wii U To Rise Like A Phoenix This October Due To 3D Mario?

It appears that Nintendo may be down, but not out of the fight completely. According to CVG and Nintendo's retail partners, Nintendo is planning to launch some high profile releases towards the end of the year such as the new 3D Mario game for the Wii U that was announced this past January during a Nintendo Direct video. The sources also say that Nintendo will bolster this with a new marketing campaign that is due out either soon before or during E3 this year as the game will be playable on the show floor. 

From July onwards we will launch a succession of Wii U titles and we will promote these extensively until the end of the year. Marketing activity will include TV, print, online and PR as well as comprehensive experiential and social media campaigns
— Shelly Pearce, the PR director at Nintendo UK

Is this enough to help the sales of the Wii U? Are you excited about a new Mario game and possibly other big releases for the Wii U coming later this year? Will it just get lost in the shuffle with the next Xbox and PS4 coming out this year?
