The Walking Dead scheduled for sometime in October. Disc versions of Season 1 (including the 400 Days DLC) and Season 2 are confirmed for retail shelves next month, followed by the premiere season of The Wolf Among Us in November.
The Walking Dead Season 2 and The Wolf Among Us are also getting retail releases on PS3, Xbox 360 and Vita, though Telltale's wording suggests they may not release alongside the PS4 and Xbox One games. There's nothing official on concrete release dates, but Amazon's been listing October 14 for TWD Season 1 on PS4 and Xbox One since June, with Season 2 dated for October 21. GameStop also has those dates listed, and both retailers have The Wolf Among Us on the new consoles for November 4. According to the listings, each game is priced at $30.
