So what is the concensus about where this Saga ends? Wano or beyond? Personally I'm not sure anymore. With the new advertisement for Magazine 10 indicating the Final Arc/Saga is coming, I wonder if Wano is certainly meant to be the end of it. I personally would have thought all 4 would clash at Elbaf or God Valley or something, unless its poised to happen in Wano?
It really depends on how Act 3 ends. If they lose and there is a slight timeskip, then i can see Blackbeard having had enough time to take whatever he took (Pluton), raid WCI for the road poneglyph and possibly Pudding (since she is poised to be able to read them with her third eye, though she hasn't figured it out), then come to Wano to take Kaido and Luffy's road poneglyph copies. Granted, this all could just happen later, but Id love it if the 4 Yonkos did clash before the end of this saga, it'd be the only chance we'd get.
I am still confused about how Rocks plays into all of this. That much is still very interesting
