Quoting ChibiKami from her Feb-4 post:
Ze 4 is being sent to the printers probably this week or next week. It being behind will also push Vol. 5. We've taken down 5 in the meantime. So expect Ze 4 in about three weeks or so. We'll let you guys know when we have a more definitive time down on it.
So, it's exactly a month since then, and still no Ze 4, or any other 801-Media title for that matter. To me, it looks like 801 Media imprint is really on a backrunner for DMP. Even if that's the case, I'd personally appreciate more realistic estimates / schedules going forward. I prefer to get a title before its expected release date rather than over 3 months after, it just creates false expectations and frustrations for those who follow a particular series or are really eager to read a particular title. Besides, we all know that these "delays" is a repeated thing for you guys at DMP. No offense and just well-intended advice: add at least a month or so to your publicized release date, esp. for your 801 Media titles as those are almost always late in the past year or so. Not always, but quite often, the past is a good teacher and an indicator for the future, so regardless of how outside of your control those factors that cause delays are, it's better to be on a conservative side with your publication date estimates.
