I agree, but time will tell
I’m hoping Atlas will be able to produce a PS3 and a TMCC/Legacy edition of the same engine. This would appeal to both sides of the O Gauge market. IMO it would be a big mistake for Atlas to drop the TMCC/Legacy license.
As far as I know Atlas only has TMCC licensing I don't think Lionel will let Legacy walk out the door. The only reason I could see for Atlas to drop TMCC is so they don't have to keep paying Lionel for the licensing now that they bought their own system in DCS.
