All valid points made by you (as usual).
I think the problem lies in the fact that some manufacturers will let collectors know their plans for releases down the road and as weeks drag into months drag into years and still nothing, they start to get torked off. Some metal companies do this, as do some of the plastic companies who sell boxed plastic.
K & C and John Jenkins Designs both have it down to a science. Andy has the dispatches each and every month like clockwork and lets collectors know a.) What is coming that month and b.) What is coming the following month, no mystery, no "Here is a picture of a prototype we are working on that will be out shortly", none of that.
And John Jenkins runs his ship the same way; he sends out an email to his dealers around the second week of every month showing what is coming out the following month and when you can order it for your customers and like clockwork, the goods show up when he says they will.
Britains also has their act together; they release two catalogs per year and let customers and dealers alike know what is coming and when and 99% of the time, the product shows up when they say it's going to.
All three companies are models for this industry, end of story..............
