I'm so happy for Jo! I definitely saw this coming once they started using her way more than actual signed Angels, when they decided to use her in the Swim Special - since that seems to be a great indicator for who's coming and going Angel wise, and when publications recently started calling her 'Angel' in their articles. I know many of them use that term loosely for any model who has appeared in the VSFS or have shot for VS, but everything was starting to add up that she would've been signed as an Angel this year. I wish they would've trimmed down the Angel lineup some more since there's still so many of them, but Jo has been a favorite for many VS fans recently, so I don't think she'll fade to the background with the other girls overshadowing her.
Vita is for sure signed in my opinion. It makes sense for VS with them breaking into the Russian market, and with her going to Ohio with Ed - which is where VS headquarters are. Besides, Ed always has a boner for her, and we all know how that goes. I'm a Vita fan, so I obviously wouldn't mind her becoming an Angel, but just like Jo I would've liked there to be more cuts before signing them.
As far as Jac and Kate, I'll for sure miss Jac and I can't miss Kate becomes they never used her! I would've liked to see how Kate would've fit as an Angel though, but clearly that ship has sailed. Lucky for both of them, they don't need VS in their careers since they're both popular high fashion girls. I would like to see Stella, Martha, Lily, Ale, and Behati gone next. I would add Adri to that list too, but VS is so obsessed with her, they'll never let her go. In the beginning I would've added Romee to that list as well, but lately she's been growing on me.
