Doing some poking around on Diamond, I *think* we have an idea what's going on. Obviously not confirmed, but a good sign.
A TON of books have moved to an FOC date of 4/20. It looks like these are the books that were scheduled to ship over the last few weeks. Shipping dates for a lot of the indie books are 5/13 and 5/20. That puts the 2 weeks worth of comics at Diamond/printers on 4/29 and 5/6.
4/29 was DC's original push date for the next week of digital comics to be released before they were pulled, so this lines up if they're going to try and get books out on 4/29 for the books already sitting on Diamond's docks.
Obviously not official, but it's interesting to see them move the books like this. We'll see what happens.
