I have no real worries about the future of MTH. I have two more locomotives on order now, and will patiently wait until they come in (patience is always a virtue, as I am finding out in training my new pup). With the MTH parts situation appearing to be in capable hands under the direction of Mike Reagan; a good number of dealers offering special runs; and some reputable service people to turn to, I have every reason to believe that this new approach should work pretty well.
The majority of my trains are MTH and Lionel . . . all of recent vintage (mostly current century). I have had a high level of satisfaction and success with both product lines.
