I couldn't agree more. Since Hornby let Tony Wright have his review sample of the P2, they have (for instance) allocated sufficient production slots to make the Silver Jubilee train pack, containing a re-engineered Railroad A4 (and a pretty good one) that was intended as a concession only item. It didn't sell, and they're not even flying off the shelves at half price.
Hornby have had a fully sold out order book for the main range P2 for well over a year now. If they make them, they'll sell, it's as simple as that.
