Chances of getting in
Simon may not have gotten a good chance at first not being from a kid friendly franchise, but that lost solidity when Snake appeared in Brawl. He also offers a moveset that smash hasn't seen yet, not to mention he has been on Nintendo consoles and a will appear in new 3DS title. So there's a considerably good chance to see him.
