OTOH, could be that MTH has decided to tread more carefully on including such features. After all there ARE other considerations in a longer term perspective....
Like costs, complexities, packaging nightmares, service headaches, storage/maintenance issues, product pricing/profitability impacts, application (or not) to smaller engines for smaller layouts/budgets, etc., etc., etc., etc.. Then there's a group.....of us....who simply cannot tolerate the steam-here-steam-there-steam-everywhere action in home/confined operation.....ourselves, spouses....
pets, smoke alarms,.......or cleaning smoke residue off from the engine, rolling stock, trackside treasures, etc..
I know, I know....not the popular opinion of 'Steam, Uber Alles!!' devotees.
So, it may be premature to think of who's the 'winner' in the features wars.
Frankly, there are more times than not that I think of JLC and his prewar/postwar products as the real winners in the toy trains world. I'm constantly amazed at how survivable/repairable/enjoyable those ol' diecast steamers are......even with their pill/oil cookers and simple piston-puffers creating smoke rings of delight. Just enough.....not too much.....to get that all-important smile from the onlookers.....including myself.
Who knows?
Time will tell.
MHO, of course.
