Don't expect any new quests just yet, though.
In fact, one has actually had to be removed for revamp purposes (Raiders in Firewatch).
Basically, the 'new' version of Map 1 will fix idiotic errors that shouldn't have been there in the first place. Nothing else. (We haven't had enough time to go through the lists and fix every floating static, for instance)
EDIT: Oh, and Prom, it's not so much that progess is slowing down, more that things are returning to normal.
Remember all the years in the wilderness before 07's release of the second Map 1 Beta?
After the Herculean efforts of the Quested release, some folks (certainly myself) are feeling a bit burnt out, and have retired to more of a back-seat position (not that I had any position prior to '07, but still...). However, we've got several new, exciting questers on the team, and once Map 2 comes out, I think my enthusiasm for proper 'work' (it's still just a hobby, though
) will return.
