I get that people are annoyed that the book is late, as am I, but looking at the big picture here it was really ES trying to be a good bro. Nate had problems with getting the art out and ES stood by the guy to the detriment of his own book. It kinda sucks that he is getting hammered for trying to let a friend get through a tough time and not just replace him. It would seem this was the sole reason for all of the delays.
Ultimately, they have a new artist and are trying to get ahead on the book before the release it so it wont suffer delays in the future. I am personally excited to read the new stuff. Yeah it's late, but I will have fun getting through the trade again and pick up with issue 7. It seems silly to hold a grudge and not read a great book just because of well documented issues that were for a legitimate reason. Why should any further delays be expected once it gets going? Maybe I am wrong, but that is the way I see it.
