I agree with this. While I'm fond of the Pac-Man World 2 design of Pac, I believe that if Namco gets Pac-Man into Smash, they're going to use the new Ghostly Adventures look before any others. They've been using that everywhere in their attempts to reboot the series (
Mario Kart Arcade,
Pac-Man Museum,
ticket redemption Pac-Man arcade games), and as much as it's not 100% successful with classic Pac-Man fans, it has been very successful with kids and new fans. They've produced tons of new toys for the series, calanders, clothing, etc., and they signed on for a season two of the show after producing 26 episodes. It was considered Disney XD's most popular show for a while, and even though Disney XD is sort of a rarer premium channel (and the majority of the shows on it are awful), that's still saying something.
Regardless of how he looks, I'm just excited for Pac-Man to be in the game. If he gets in, I swear he'll be the only character I play as. I might stray here and there to try out the other characters, but I'll always go back to Pac-Man. Even if he's awful. xD
