This whole Two In One series is built around jerking you guys around expecting the Fantastic Four to return. That's why it exists. Once they're reunited the FF gets a new series and this book is over.
This book exists to STALL the return of the Fantastic Four not herald it. As long as it goes on you're not getting the group back. Whatever deals need to be made to bring the Fantastic Four back have not happened. This series buys Marvel time while they get their crap together. This series is just a bone to throw FF fans who are sick of how the Fantastic Four have been treated.
I wouldn't expect to see the FF back this year. They're going to milk this Two In One stuff as long as they can.
I originally thought that, too. So I am being a cock eyed optimist with this article. The release of all these trades is the main reason. Not the issue hype with issue 6 release. Notice the two Dr. Doom's on Cheung's cover? I'm wondering if they are not going to end up on the Secret War's recent Battleworld again? From there they see the truth of the events that transpired at its end and still continue on a quest for Reed, Sue and the kids. I could see it happen. Doesn't mean we won't see the return of the FF this year, but, I do not expect it to happen immediately after this issue.
