Seems like the general consensus is that Zelda, Xenoblade, Splatoon, and Star Fox are the most anticipated.
Myself, I will get Xenoblade in day 1.
Mario Party is always fun, but not sure if worth an early purchase. Splatoon and Devil's Third look interesting, will check them out. And Yoshi is just charming.
All the others I'm not interested, unless Star Fox is within the likes of Adventures/Assault.
