Do you think the Ravenwing Black Knights will be a standalone kit or an upgrade sprue?

A lot of signs point that the Ravenwing will get a revamp in 11th. I’m very excited to have updated mounted unit alongside my Outriders and ATVs. How does everyone think we will get them? Will we see an upgrade sprue made for the new Outriders kit like we see with Deathwing Terminators or are we going to get an awesome new kit that will, hopefully, complement a revamped Samael? Interested in everyone’s opinion and the pros/cons of each method.
