Nintendo pretty consistently announces release dates around 2-3 months before the games release. So...it will all depend on when those games are ready, but I wouldn't get your hopes up for getting a whole slew of release date confirmations all at once. Yoshi's New Island just got a release date announcement all on its own because it comes out in a little over 2 months. If they do a Direct this month then it's likely we'll get Mario Kart 8's release date. If not, then it means MK8 won't come until April or later. If there's no Direct, same thing. MK8 will most likely be the next major release after Donkey Kong (at the end of February) from Nintendo for Wii U, so all those other games will probably be May or later. I strongly believe that Hyrule Warriors, X, Super Smash Bros, and Yarn Yoshi will all release in the 2nd half of 2014. Bayonetta 2 is a wildcard...that one COULD come out in the 1st half. We'll see.
