True but there isn't it seems going to be four separate minis per character (Nova, Silver Surfer, Ronan and Super Skrull) for this new one, just a Alpha and then 6 issues. In which case its likely it'll be one writer, two at best (co-script or otherwise). Of course I'm also curious who the artists will be. Divito did a good job on Annihilation itself but the art of the initial four minis and Annihilation Prologue wasn't great, save for Kev Walkers' Nova.
That's just the event itself, there is a chance we might have other parts just not collected in that tpb.
It's not like Marvel to just do a mini series, and while my wallet would welcome it, it'd be a departure from how they usually do things
