I have always felt since the King announcement that supporting the crowdfunding could eventually lead to more models from DJM. Obviously not all will either want or be able to afford any future models, but having another producer of models has to be good for everyone. I'm sure an eventual Mogul would be well received, especially if the King turns out to be a real cracker!
I am of the opinion that of the current two main producers of N steam, one may possibly drop future steam releases in N and concentrate on O gauge. Nothing to back this up, just a hunch on my part.
I eagerley await future updates from Dave, as I'm sure many others will be.
