Everyone who hadn't submitted their part was replaced, and with upcoming deadlines. That was the whole point of the front page announcement and this "Round 2." I've just updated the first page of this thread, and currently nine parts are being waited on. I still consistently use the spreadsheet, and though some of it probably doesn't make that much sense without a key, all the parts in light green, that track the builders and their submission of parts, is up to date. The macroblock and consolidation columns are less updated, but actual consolidation of the parts into the map has kind of been put on hiatus as it's much easier to edit the map with fewer parts in the way.
As for expectation of release, there's still a long way to go. Post-production is going to be massive, as this project's even larger and more intensive than D25, so even once I get all the parts it will take a fair while to get the map release-ready. I jokingly said a while back that we should aim for the anniversary of the release of valley for release of the map, but I'm going to herein seriously set that as an absolute-latest deadline.
Although it may seem a little lazy/pathetic that it's taken since November to get this far, I've been working on this project with re-invigoration, and so there should be steady progress from here on out.
