I hope I'm wrong but I have a sad feeling in my gut that tells me no Gergiev conducting equals no filming
The casting of the Tereshkina/Shklyarov performance, with Kondaurova as Lilac and Kolb as Carabosse, on the 8th, seems to have been made with filming in mind so who knows. When do people usually find out if a performance is being filmed or not? I feel like with a week to go we would have already found out.
They performed it this ballet 10 years and then dropped it without ever releasing a DVD/Blu-ray (other popular ballets still performed have one!). Now with it being revived for the bicentennial (and likely to be dropped again once its over) this will be the very last chance of capturing the whole ballet on celluloid. I really hope they don't throw the chance away otherwise I'd assume their personal hatred for it clouds their judgement.
But as I'm sure you know in the "Sacred Stage" documentary they have parts of the Prologue and Rose Adagio (with Zhanna Ayupova) professionally filmed. They also have the whole vision scene (with Zhanna and Anton Korsakov) as a DVD bonus. I've always wondered if that whole performance was actually filmed, for the documentary producers to pick and choose clips with permission, and its now lying somewhere in the Mariinsky vaults gathering dust.
