Coming from a Nintendo email...
The Nov. 8 launch date for Mario & Sonic at the Sochi 2014 Olympic Winter Games that was recently listed in a Wii U notification was an error. A confirmed launch date will be announced in the future. We apologize for any confusion.
Our year-long sponsorship with Nicalis is ending today (May 31st, 2016). We would like to thank Nicalis for their support over the last year, keeping GoNintendo ad-free for 365 wonderful days. It's been a pleasure to provide all of you with an ad-free year, but sadly we must now return to a more traditional ad-sponsored layout. That will be happening later tonight.
