Well just because Selita, Izabel and KK aren't angels doesn't mean they won't appear in the catalogs, or shows. It just simply means they won't be making the money like they had before with vs and no launches.
Victoria's Secret most of the time keeps girls who sell products extremely well. Adriana and Alessandra are their highest for selling products, as for KK I always knew she did so-so with that, not as well as say Adriana or Ale but not bad either. I agree that the spilt was most likely mutaual, her contract expired in march so realistically she's not been an angel for a while, same for Selita. Selita quitting VS would be explanation for the dramatic hair change as well considering one of VS's big things is not changing the angels appearence. She could have known about it and only then decided to do it considering she would be trying to get new work.
So the angel line up now is what...
(Not counting Heidi, considering she doesn't even do anything)
Adriana
Alessandra
Miranda
Marisa
Doutzen
Emaneula
I will say that I love the number of angels a lot better, and I think this group will do just as well. I still wish they would drop the show for a year and do a tour, to introduce the new angels and etc.
