I'm tagging this "Rumor" because it could be a mistranslation, but in an interview with Entertainment Weekly, Miyamoto said something of huge interest to Star Fox fans.
It started when they asked who Miyamoto would play as in Smash. He said "Star Fox" (C'mon, Shiggy, you should know the character names in your own creations!) because it would be harder than playing as Kirby.
It was the next question, though, that suggest more was coming for Star Fox:
Q: You prefer a challenge.
A: This is gonna be the year of Star Fox. Iâ€™ll play as Star Fox for awhile.
Wait, did he say "The Year of Star Fox?" I fully admit that the statement may not actually mean anything, but for the Love of Lylat let this be true!
