I don't think there's a thread for this yet, but it's coming out Monday so I thought there should be one.
Or it WAS coming out Monday. Robert Boyd, co-creator, was interviewed on Active Time Babble (good episode, gender and LGBT issues in RPGs) revealed that while the PC version will indeed release Monday, it may be a little while for the XBLIG release because someone found a very minor glitch that forced another attempt at certification, which can't be submitted til a week after the failure. I really think I should get around to playing the first two episodes, so maybe this'll be a good chance for me to do so. Unlikely though, as I bought on Steam but never play any damn PC games.
He also revealed that there will be a fourth and final episode starting development after this, targeted for release around PAX West next year.

If you buy in the first week you get a copy of Zeboyd's last game, Cthulu Saves the World, for free.
If anyone else has something they'd like added to the OP let me know.
