Super Nova vs current Silver Surfer. Battle takes place on a.... Ah who are we kidding? With these two beasts, the battle takes place where ever they damn well choose. Who takes it?
Well he does... sorta. Apparently what they've done is allow him to access his full power in short stints. That's why he was able to amp and then push back against Sphinx's blasts for a few seconds.
It would be interesting seeing what happens if he's tapping into his full power (And you have to wonder why Worldmind didn't give it to him in their first fight instead of just rattling off how Surfer isn't one to be trifled with..)
Not sure if he fights the surfer. But supposedly we can expect a nice "conversation" to occur between Nova and Gladiator regarding Glads and his treatment of the Centurians during the WOK.
