Oh and yea, it seems unlikely that luffy would be able to beat the comming characters without any major powerups, whether it's gear 4/5 or new haki abilities or something completly new. The idea that a new df seems likely, but Luffys fighting style is already quite refined. so I doubt he would get another one. But I agree with Luffypirateking that one of the "only" options for now is a new df.. And we have the arguments with us to luffy being able to wield 2, instead of just calling it ludicrous.

Anyways this is theory is not" ludicrous but also impossible"-.- since all the "facts" points toward it being possible:)
