Like all content, its there to view if so inclined. What it brings out for me is how early in the TT:120 journey we are, and in respect to a new/old gauge release, what have we got to compare it against? How long did N or OO gauges take to get going?
If Hornby folds, I would feel disappointed and concerned with what I could financially lose with what I have invested so far (2nd time around), but would it be reasonable to assume another company would consume the brand and/or produce their own TT product to fill the void? Likely I should think.
I think, lets see how the gauge builds, how they address quality concerns with locos, decoders, etc, and establish a gauge they have near total control over. You never know, other manufacturers may already be looking at new TT lines themselves on the back of Hornbys success with it.
