I think we were told that they wouldn't be back on track with those until after #150 is out the door, since essentially they're doing double duty at present with Dungeon and Pathfinder.
I hope it's soon afterwards. I'd really like to run it, but I run a Realms game and it'd be stupid for me to start it and then get stuck stopping it at AP #4 until the rest get done. The players will lose interest, obviously.
It'll be a while. Keith and Eric still have to write them. I suspect the project fell off their radars, actually, and until Pathfinder #2 is caught up from losing 2-3 weeks from its schedule to the last Dungeon, I wouldn't even have a chance to edit them.
Eventually, I really, REALLY hope to have conversions up through the end of Savage Tide. But again... it's gonna be a longer process for those (always has been) than the art/map supplements.
