I think it'll be 24, that just feels about right. I know Mortal Kombat did 4 DLC characters, and I think 4 is about as much as a studio can do before they're really "overstaying their welcome", in the sense that they're not working on a new game which is eventually gonna catch up to them.
The next two will probably be paid, and they'll hopefully be big-ticket characters to warrant the fact that we're paying for them. If Superbot could cut deals with Square and Activision, I think everyone would gladly pay for those guys! : D --- If I haven't mentioned Kat in my post, it's because she is so beautiful and precarious that I just wanted to show her how much she means to me.
Im thinking 2 more characters and other stuff non character related --- I wish Blastoise was my dad. He wouldn't beat my mom like what her boyfriend, Johnny does. If Blastoise was my dad things would be different around here.
