Sadly I don't think so at this point. I expected one during Wano, a short one at least. The WB pirates are criminally neglected and just done downright dirty by Oda and then some.
The Weevil storyline gave me slim hope but that went nowhere. We've still not seen the payback war and I doubt we ever will now too.
I'd love to see how he met Oyaji and joined him, I remember seeing a sweet fanart showing him joining WB. Marcos respect for him is really sweet even though his attitude towards WB at Wano angered me and felt OOC.
Marco is the GOAT though, pineapple phoenix doctor man. I would have loved to see him get awakening and the full potential of his fruit but him vs king and queen was freaking awesome though.
Oda could surprise us but I'm not getting my hopes up. It's interesting how Shanks wanted to recruit him twice now. Maybe we'll get more on him in Shanks or Blackbeard arc but I'm not hopeful. Weevil being offscreen captured was absolutely awful writing, just like him targeting the WBP and allies in "revenge" and also offscreening them too.
I loved the theory that Marco was alive for centuries being reborn by his devil fruit constantly and thus being much older than he appears and thus "Oyaji" himself ironically. Would have been hilarious if he was the egg on Roger's ship somehow if it were ever possible.
