Millie will do more with ASOS and Teddy with Jack Wills (those are the only noteworthy deals) but no, I don't think anything big and new is going to be announced. Kaz and Faye will probably do some TV with varying degrees of success, Chloe will do well with YouTube. Influencer culture is dying, these people don't have half the fans or charm the Season 5 lot did. The only ones who will be remembered are Toby (but he'll have no career other than the remnants of a Bohoo deal) and then Faye & Jake for all the wrong reasons.
I predict Chloe and Toby will break up in the next couple of months, and Millie and Liam will be somewhere between one and two years, if Liam can keep his dick in his pants. Faye and Teddy I don't know, they're so volatile (and love fan attention). If they make a full year without Faye ruining it I can see them being the longest lasting but they also could break up tomorrow and it wouldn't surprise me.
Millie will be the only sort of long term successful one IF she keeps her mouth shut - I liked her on the show but she comes across very stuck up on instagram.
