DCS isn't dead...actually it's now being installed in Atlas engines instead of TMCC. I get so tired of the fanboys that feel it necessary to push their narrative! It wouldn't surprise me if they went door to door with this tripe.
As for MTH DCS, I too would love to hear the latest from the west Michigan group.
Atlas will continue to offer TMCC (ERR) in their Trainman and Master models in addition to PS3 in their Premier models. I have to give credit to Atlas for appealing to everyone, including me who runs 2-rail DCC.
DCS will carry on and will remain a player for years to come. I don't think Atlas would've considered acquiring the DCS license if it was otherwise.
