I'm one of those who believe One Piece holds information that can destroy the World Government by its very foundations and justifying why WG jumped the gun on Gol D. Roger and anyone associated to him even by being his son or building his ship, so I definitely see Marine vs Pirates on a scale that not even us OP readers ever saw. I wouldn't be surprised if took a good chunk of years entirely on that arc.
