There are Lionel and MTH software “camps”. Atlas will probably try to accommodate both (read not alienate) As Long As it Makes ECONOMIC SENSE !!! And to do this, everything would be BTO and probably require a non-refundable deposit. Juggling the two systems will add complexity to the manufacturing chain.
Which system is scaleable ? That is, which has the best ability to be easily changed/modified/upgraded ? That might be the winner. Remember. They want to make money. To make money - simple always wins.
I Sure Don’t Know where the software situation will go. Time will tell. Help them decide and step up and buy some of your favorite products as this unfolds. In a way - you get to vote with your $ spent.
All - IMO 😬
PS The Real Key here is the FACTORY !!! Think about it !!!!
