you should ask in the console forum, this is a thread about a19
but long story short (for what i know and remember) TFP sold the right for a console port to Telltale, Telltale stopped updating and then went titty up, TFP after a legal fight win the rights backs(or buy back, don't remember), maybe after gold TFP could think of porting to console (emphasis on maybe)
updates were all responsibility of Telltale, not TFP
