Your point? I'm certainly not going to defend a possible fake image using the logic of superstition but to write it off because he isn't Nintendo and from Sega is absurd logic. There are no patterns, there are no rules, all that matters is what Sakurai feels is best. As I said, and I don't think this can be argued, if one third party franchise could get a 2nd rep, it would be Sonic. Plus, Tails actually makes the most logical sense. He's the only Sonic character who is often used and a focal point to the story since Unleashed, outside of Dr Eggman. I can certainly see the logic of adding Tails to the game.
Like I said, I don't believe this leak yet, and basing it on a banner is nonsensical but there is nothing stopping Tails from being a Sm4sh newcomer. I think the more interesting thing would be how does that change the 49 character roster. If Sal is right, we'll be at 36 characters. 13 missing Brawl vets, sans Squirtle and Ivysaur. To include Tails would likely mean either an RPG column cut or a retro character cut, perhaps even a Spacie/Techno cut, as all 3 are places Shulk could go in. Well, that's moot speculation for now, after all, we still don't have conclusive proof one way or the other on the Best Buy demo, and this Tail image must be placed under greater scrutiny outside of "He's Sonic, he can't be in, they can't have two characters"
