I hope we see a DC universe overhaul like the SFMM section, which is the rare nicely themed SF addition. Retheming Nitro would be an easy overlay, and perhaps they'd throw in a giant frisbee themed to Wonder Woman or someone else.
Also, Zash, agree wholeheartedly. I love GAdv because I love pretty much any theme park, and because I grew up on it, but it's hard to deny that these days Hershey and Dorney beat SF on safety, cleanliness, efficiency, and just about every other area other than ride infrastructure (and even that's debatable depending on your preferences). I recognize that not everyone is in a position to think this way, but I'd personally absolutely prefer to pay more for the better product.
