Well, you'll never know until the game comes out. Even when it seems unlikely, Sonic managed to return despite Mario not being put in Sonic and Sega All-Stars Racing due to Nintendo and Sega deciding to only have Mario and Sonic to meet at the Olympics. Now that Sonic is in two Nintendo All-Star games, Mario needs to be in a Sega All-Star game because Sonic is overexposed to Nintendo. And Toon Link was seen as a stage cameo on the Spirit Train, but was confirmed playable a couple days before Sonic.
