Bonhams: "The most important item in the Geddes collection"

The Bonhams press release for the sale of the Graham Geddes Collection later today quoted Chantelle Waddington (Rountree), the head of the antiquities department:

The most important item in this collection is a vase by the famed painter of the 'Berlin Dancing Girl', a vase of incredible quality and condition, which marks the transition of Greek vase painting from the Attic to the South Italian.

The piece in question is an Apulian red-figured hydria (lot 10). The estimate was £80,000-£120,000.

Why has the most important piece in the collection been withdrawn? Is another press release due?
