There was talk about Daisuke Takahashi returning to Nikolai Morozov already five weeks ago in Moscow. At that time his agent didn't confirm it (but didn't outright deny it) when I asked, but now I was told to expect a press release tomorrow (Friday). I am thinking this will be the official confirmation. But maybe Morozov is not doing his choreography or at least not all of it. AFAIK Takahashi is working with Lori Nichol (but I don't have an official confirmation for that either).
