Who were you hoping for?
I was very surprised that Nairo, the most popular Smash 4 player, didn't get invited. We don't even have a USA rep for smash 4. They also felt the need to invite melee players when the chance of them dropping soon after release is high. And if we had to have melee players, why Mango instead of M2K or Hbox? Smash is my favorite series, so I'll still watch, my hype level is just decreased a little.
