It's funny, I actually expected the complete opposite with regards to E3. I didn't expect Pac-Man to come at all, but Palutena and Miis were pretty much givens for E3 as far as I was concerned. Although the form the Miis took was a pleasant surprise, I think.I did not really expect Palutena or Mii Fighters at E3 specifically myself, albeit Pac-Man was given.
According to most people, there are only three options. I doubt any confusion would ensue. On the other hand, there will be a lot of debate as to whether or not the character was indeed "filler."
