Diamond's got themselves to blame. You can't effectively hold the entire industry ransom and then declare you're going to extend the supply of new product to struggling shops just because you can.
If Marvel joins in (which they absolutely will if DC is still going strong with it after the dust settles), that's probably it for Diamond having such a choke hold on the industry. What I'm more interested in following this isn't so much if Diamond lives, but how the much-needed competition shapes the industry into something that's hopefully stronger.
