So I used to collect the "Marvel Essentials" TPBs. I loved them, they were cheap and had a lot of material in them. They've apparently cancelled the series and are replacing them with the "Epic Collections" TPBs which will be in colour and cover the major story arcs for each character, but not every issue. And they aren't releasing them in order, which is sort of weird. It kind of hurts, I wish they had at least finished the Essential Marvel Team-Up books. They only had three left and they waited so long between volumes. Sigh.
EDIT: actually, they may contain all the issues after all. But so far, there is only Amazing Spider-Man titles, and each of them have a few tie-ins from Spectacular or Web of. I wonder if they're going to do Epic Collections for each title.
