Obviously this guy is not used to Telltale's release model. Yes, the next episode is a month away because it's still being worked on - that's what Telltale do. Generally they are working on 3ish episodes at once so right now chapter 2 is coming to a head, chapter 3 is going into production-proper and chapter 4 is being written, most likely.
This model allows them to do a swift and steady series of releases over several months. It's a very efficient way of working as compared to many other studios that have tried to do episodic content!
