Well, the general storyline about Project 7734 continues into the backup feature (although it took several months of very strange stories there to "get" that), so if they didn't put it here then Superman readers would have to pick up some other book just to get the full view of what's going on.
So far, the storyline itself is very "meh", but I'm hoping it dovetails into the bigger plotline soon and starts to actually affect what's going on.
Oh, and hopefully this completely retcons the incredibly stupid Countdown stories with Monarch!Captain Atom. Those made absolutely no sense, at all. I think blaming it on anal Skrulls would be fine with me at this point.
