Since no one would go to Firebird to see Hallberg (my theory), removing him poses no consequence. I doubt many people would notice, or even know that's he's injured again, and then deduce the odds of him making Giselle (other than hard core balletomanes, like on this site). Or, that's what the company is betting on. I'm sure he and Osipova will remain on the calendar as long as possible, so people will snatch up tickets. I really hope he's well enough to dance, but the signs aren't good.
