I know it might be a long shot, but since there were rumors of Web Warriors-related characters showing up in the Clone Conspiracy (but so far as I know this never happened at all)...
The only top-secret bonus creative team I can think of who would NEED to be top-secret--and, yes, Ron and Tom, I know you can't confirm it if it is you!--would be Tom and Ron. Because that would basically give away that Mayday is involved. I will say that I am not spending $10 on a long-shot hope that Mayday is involved, but oh man, it would be so awesome if she's coming back...

This also intrigues me. Again, a long shot, but if there was going to be, say, a crossover with the MC-2 universe, well, a collection of relevant stories might just be too much of a tip-off. Of course, again, it's entirely possible that I'm barking up the wrong Groot, as it were...
