She won't get the cover, not a chance. I adore Anne and she is by long miles my favorite SI model but 2014 will be the magazine's 50th Anniversary and they will go big for it, they already did a shoot with former cover models (Tyra, Paula, Bar, Brooklyn, Marisa, etc) and I think that's most likely going to be the cover. I'm sure the cover will be Kate Upton with some of the former cover models.
She also said this year that she is going for the record of more times doing SI which will be 13 times by Kathy Ireland and 2014 will be Anne's 10th so I'm pretty sure she'll stick around for as long as she can, I don't think she'll retire from SI without scoring at least one cover
