I wonder if the cinema broadcast was cancelled because the lighting and special effects are so complex that they might not translate to a cinema screen. And that might also make it very difficult to tour. I believe this is a co-production with National Ballet of Canada, so eventually it will be seen in North America.
The ballet is still being broadcast live, it's only the North American screenings that are being delayed, postponed or whatever the deal is. But I think you're right about the National Ballet's performing rights. It, and not the Royal Ballet, brought Alice's Adventures in Wonderland to the Kennedy Center. The Canadian premiere of The Winter's Tale will take place in November 2015, and if that ballet gets any North American tours, I imagine that the National Ballet of Canada will be doing them.
