How is Rita Ora a lock in? I'd consider Azealia to be more of a lock in than Rita.
Lana is for sure. But no one else is quite a lock in like she is. It's still up in the air.
I think Lana has a worse chance than Rita, honestly. Rita has Roc Nation behind her and is something fresher for a pop market and caters to that market. She has a look MADE for pop music, and is the European Rihanna (Rihanna = Barbados, Rita = Yugoslavia). Lana has Interscope (who only really support Gaga, let's be honest). She also isn't meant to be a popstar. But who knows, maybe she can help reinvent the "image of pop."
