Now that it's confirmed(?) that you won't be forced to play as Pikachu, I'm actually hyped for this game! And even if we can only play as Pikachu, the Unova starters, or Axew, it's much better than only being able to play as Pikachu.
The only Mystery Dungeon game I've played was Red; I was never able to get the newer ones but I've always wanted to continue playing them. This seems like a great opportunity for me to get back into those games.
