As the previous poster saying about the RA, I think Sabo survives and joins them. I mean they were in the flashback. They can't possibly have such a small role as they had in the previous chapters, they didn't do much at all in the flashback.

And Ace saying "The Sabo Incident" doesn't mean he actually died, it only means THEY believed he died.
