Unless they come up with something that I REALLY want, I'm at an age where I no longer pre-order from Intermountain, since none of my heirs is a model railroader, and even if I am still around when the stuff finally shows up, I don't know how many more years I will be able to manage getting up and down the stairs to the basement. Also, it would be a HUGE help if they let us know HOW MANY more orders they need on the stuff they list as "need more orders"- do they need 5 more or 2000 more to get to whatever their minimum is. I might only want 2, but if an order of 5 would get it done, I would consider it. Conversely, if they need 2000 orders in the next 4 weeks, because they only got 500 orders in the past 4 years, I will write it off and order something else.
The two sales models I see as actually successful (although I don't think anybody is becoming a billionaire) are Micro-trains and Bluford. MTL releases 10 or more N scale cars most months, and in addition various runner packs and special pre-orders. Bluford generally announces 1 body style at a time, each released in several roadnames and multiple numbers - I think the last couple of announcement to delivery times have been stretched out to about a year, but pre-pandemic were shorter. Which is to say- they have a limited window to get your orders in, have actually produced almost everything (I think I read somewhere they had canceled 1 roadname of 1 bodystyle) they ever took a pre-order for, and their pre-order announcement to delivery time is less than Intermountain's time from "scheduled for production" to "in transit".
Why on earth Intermountain thinks its system is superior to that of MTL or Bluford is beyond me. I assume it works better in HO.
