Just found another cool hack:
I got this funny feeling that the reasons for Snake and Sonic's inclusion in Brawl are gonna be the same reasons why two other third-party characters are gonna make it in the next one. This is what I think:
Travis Touchdown: Yeah, I hate to admit it but something's telling me that Suda51 is gonna do exactly what Kojima did for Snake; personally request his character to be in the next Smash Bros. game. After what he said months ago, I really got no doubt that he'll do what he can to have his own character in it. I personally got nothing against Travis Touchdown being in the next game. He would be an interesting character but like I said before, he's still pretty new and needs some time to be a big star, which hopefully by then, he will. Afterall, he is starting get a fanbase so it just might happen.
Mega Man: This is something I truly hope is gonna happen. Like Sonic, Mega Man might make it in through the most votes. After his absence from Brawl, there were PLENTY of disappointed fans, like myself, who wanted to see Mega Man make his Smash Bros. debut, only to realize that neither Nintendo or Capcom contacted each other. Thus, in order to make sure he doesn' t miss out this time, I predict that he's gonna be the most requested character for the next game. I don't really know how much votes he had for Brawl but if anyone does, let me know. If they were high, then he has HUGE chance of getting in the next one.
