I don't think there's anything to worry about. Assuming any of the speculation is right, they've already been working on things for at least a few months, and they're not going to throw out the time and money that's already been spent just because any intended "surprise" might be less of a surprise. All we have right now are still just theories, and even assuming any of it's true, I'm sure they'd just be happy that everything's getting such positive reception.

The only thing I could see having any effect on would possibly be the "Adult Swim Jr." name if that theory is right, since it's gotten somewhat mixed reception. I'm fine with it, but if they did change it, I like the suggestion I saw somewhere else of "young [adult swim]."
