Evan earned a bye b/c he won a medal at the last Olympics. If he WD, there will be no replacement skater.
It has been said by the USFSA that he needs to have the minimum TES score BEFORE Nationals in order to be considered for the Olympics. His last opportunity to do so begins on December 10. So basically all we're waiting for now is the withdrawal announcement (though no doubt he will leave that as late as possible, and the replacement skater will be disadvantaged ).
No doubt in the meantime he'll still be milking his sponsors with the "I'm going to Sochi!" line...
