A shame, but the problem, I think, is liveries are so fragmented for buses. I know I'm not interested in a bus unless it's in a livery I want, and that's a short list of one. No manufacturer could produce hundreds of tiny runs of each wanted livery for any bus, so interest is very likely to be low on initial announcement and only prove out in the long run.
For the record, I'd have two of these in the Wilts & Dorset livery (red white black), but probably not many more than two.
