Calgary Worlds
Assuming Arakawa and Slutskaya do not attend, I think the potential biggest threat to Cohen is Kostner (assuming she goes). If she is not totally demoralized from her terrible skate in her home country, Caro has the basic skating and technical goods to be WC and she will be under a lot less pressure than she was in Turino. Caro will need all her 3/3s because presentation-wise she is not in Sasha's class, especially given the quality of Sasha's LP this year. The other potential dark horse is Rochette, who in spite of some mistakes finally showed her potential in Turin. Unlike Caro, she tends to skate better when performing in her home country. Fumie I think doesn't really have the ability to overtake Sasha unless Sasha has a meltdown -- Fumie's jumps are generally about equal to Sasha and she is way behind in the spins and spirals dept.
I would love to see Sasha win a World Title. Her LP this year is a strong one and championship worthy if skated well. Still, a U.S. National Title and Olympic Silver Medal are nothing to sneeze at.
With regards to the media, I have seen an equal split between criticizing her for choking again and others supporting her for not letting the program go after the early mistakes. I could see her getting some PR mileage out of this if she plays her cards right. It obviously won't be the same as if she won gold, but she potentially could do pretty well.
