Scott's in a unique position as he actually uses some of the ERR products himself, so he certainly has a vested interest in the line continuing. OTOH, the additional ERR products that don't get used in the 3rd Rail product line will have to stand on their own as far as volume and profit margin, so proceeding with some caution makes a lot of sense.
Given the die is cast and all that about 20-20 hindsight this points out how this would have worked out better for all had the transfer to Scott been made before the announcement. He could have acquired ERR's remaining inventory, 6 months worth we are told, and been up and running as soon as his staff was up to speed on custom programming the boards. He would have a gauge on what products are selling or not and then order as needed.
