After SSM Brawl,..

I know it sounds silly to be thinking about the next Super Smash Brothers when Brawl hasn't been released yet, but I wonder what the 4th version's name will be. Maybe reduce it to just "Smash Bros."? Use a term like, er, Donnybrook? (That's a hockey term for multiple fights at once.) What do you guys think?

Maybe go more detailed like 'All out Battle!' or something?
