That is really good news. After multiple 1:1 conversations over a few years with a couple of their muckety-mucks, I had completely written-off ExactRail as a player in N. The way it was expressed to me was their N sales experience was a drag on the company and they had "no plans" for anything new for us. Maybe they actually heard similar things from others, "no, nothing to do with the scale", it was their choices of prototypes and the duplications of other fine products.
I am hoping beyond hope for the GSC flats. They did an amazing job on the HO version.
