For your information, there is an interview of Polunin on the latest issue of Shinshokan Dance Magazine which was taken during Alina Cojocaru Dream Project in Tokyo (February).
In this interview, he says that he has been contacting (from himself) several ballet companies such as ABT and Russian companies, and there is an offer from a new Broadway musical with him on the main cast and also some choreography but he can't tell details yet.
So it looks that he has not lost passion in dance, but he says he saw no progress in himself as long as he stayed at the Royal Ballet. He wanted to push himself in an unstable situation.
He is set to dance a full Don Quixote with Tamara Rojo this summer at the prestigious World Ballet Festival in Tokyo. Has he danced a full DQ before?
