There is a second season being made, but that's not until next year. The only thing before then I can imagine being done is Telltale preparing a CD containing all the episodes for PC players like myself, (it makes sense as that would make it a Christmas holiday release), badly needed by the way since with TWD and for the first time, they've stopped making available to us as individual downloads separate install files for each episode to keep on our computers. (We were forced to use their awfully bugged, badly coded, save-game demolishing download system--the inverse relationship between the quality of the game's content and that of its coding vis a vis savegames, facilitation of downloads and installations, and choice continuation--add to that customer service, communication, and QA--was phenomenal.)
But perhaps you've heard something I've not? Where did you get the information?
By the way, have you played it yet, Asterikos? I'd recommend the PC if not, simply because you have the ability to back up your save games in case anything happens.
