Did I say it hadn't?
But you expect full-on 1v1s, which you ain't getting, not even for a single panel.
Instead you'll have the main event of the island, either Garling showing off or Xebec losing his cool, surrounded by a couple of clashes a la Marineford, with characters getting in the way of attacks and leaving it at that.
Even the Xebec vs Roger & Garp you aren't getting, aside from a cool end-of-page pose.
