It's probably because of the rise of some other "new" models, like Karlie and Joan. We just need to wait until the actual supermodels who are kinda "old" (Anja, Lara, Sasha) decide to end their careers and she'll have more space. When Lara Stone will be gone (I feel like it will be soon) it will be between Freja, Natasha and Anja I think. She just needs to have a strong comeback after her little break
I really don't think that it's not gonna between Anja, Natasha and Freja. Most likely, Natasha and probably Anja/Sasha will also be removed with Lara (it would be kind a weird, Natasha is I guess even longer in the industry then Lara and especially with her L'oreal contract she will move).
Freja not, cause she isn't working at the time. It will most likely then go between Karlie, Joan, Arizona and Freja if she is back on time.
@candlebougie: in all fairness Josefien Rodermans does look a LOT like Freja. But still for a magazine is a sad mistake
