Interesting observation - of course this leaves us with, what could possibly come after the Team-Up. Based upon "paterns"?

I wouldn't expect to see anything with a Spider-Man headliner (Volume 1 to Volume 150 - next would be volume 300?).

I also would expect it to be an ongoing title since volume 50 and 150 lines have only so many books within them to print. Spider-Man is ongoing and it could be argued that Defenders is "ongoing" since there is a second series (Defenders Volume 2 Number 1). I can't think of another ongoing series that we can stick in there.

Having said that, there aren't many GA titles that have not been started yet, many AA and quite a few MA titles to choose from. What other genres are still out there? Crime?! I don't see that one. Comedy? I REALLY don't see that one either.
