l don't think there's an overwhelming number for sale, if you look back at an old copy of MCN from last year its still the same.
More a case of nothing much sells over the winter months.
Ducati's remain very desirable machines, to the cognoscenti but do not have the same mass market appeal of Blades or R1's. Maybe the same as Porsches against VW's.
the difference is often someone may desire an icon such as a 916, but will still buy a Blade for a variety of reasons, not least cost, perceived reliability etc.
Every product has a price at which it will sell, even old CZ's.
Not every used Porsche sells immediately.
Enough deep thought, its Friday and time to start the stag weekend in the pub soon.
