Soooo, lemme get this straight. The "major" event based releases for PD13 were divided into ten. The first release started production on December 6 (after the cover art was posted) and it has now been three full calendar months. Meanwhile production on the second of ten parts for PD13 is about 25% complete while the first part is still 3+ weeks away from being completed, so now he hopes to release them both at the same time, at the end of March (which probably means after the first of April because ...). So that would be two of ten, 20% of a PD, released after about four months. Together. But of course that can't be guaranteed. So it's a maybe? Fine.
This information seems to contradict every expectation that was previously set for PD13. I get confused easily so if I have this wrong please do help me get back on track.
