I feel like Batman has made it big in the gaming side of things because of Arkham Asylum and Arkham City. He's not just one of those guys who gets movie adaptations, he stars in legit innovative GOTY games. I think he has a decent chance of making it in. There's still about 14 characters to be announced, I'm guessing 7 are 1st party and 7 are 3rd party.
It won't be 7 and 7. Third party is playing a part but it won't be on par in regards to characters to select from. It'll be more like 9 and 5.
