This comes from the announcement made in May that The Walking Dead: Season One and Two and The Wolf Among Us would be coming to PS4 and Xbox One later this year.
It should also be noted that the retail version of these games for PS3, PS Vita and Xbox 360 will also be released in the same month as their next gen counterpart.
I can’t wait to get The Walking Dead in October as I have only played Episode One – which I loved! And of course The Wolf Among Us in November, as I have heard good things about it, but never played it. I’m just happy that the games will be released soon!
