I've seen early drawings of Oda giving Luffy an awesome pirate coat (worn by every major pirate captain thus far in the series, and in case of absence, a simmilar coat is also present) that seems part of the "Pirate King" wardrobe, so I was wondering if Oda was actually going to give Luffy that coat in the series. Thoughts?
It seems more plausible than Ganzack appearing (oh, but I sure would love to see our beloved Pirate General) or Luffy getting Skypiean/Shandian angel wings (as was depicted on one tanko cover), but it's fun to speculate about.
Maybe the pirate coat was extremely early foreshadowing; I know we did not see Kabuto in the manga until many chapters after the "Pirates v. CP9" colourspread.
