To me, the answer is simple. Release these hardcovers to your hearts content, but a couple months later, release a softcover collection. Charge $15 for it. For those non hardcore collectors who just want to read a good comic, this would be a boon, and I believe theyd sell well without hugely cannibalizing the hardcover audience, and help readers like me catch up on the book instead of just continuing to ignore it every month.
This makes far too much sense for either Marvel or DC to bother attempting it.
That was an interesting read. I actually have the first Thor: God Of Thunder trade in paperback but I guess that's because here in the UK it's published by Panini Press.
Really though, the fact that I bought both East Of West and Five Ghosts for just £10 within a month of the end of their respective story arcs, but I'll have to wait until March to spend £16 on the third Flash hardcover (collecting a story arc which ended, what, 4 or 5 months ago), with a paperback probably not until next Christmas or something, is just utterly ridiculous.
