They just said that they planned to go to Zou, Law was against it.
Please read up
You missed the point of my post completely. It was supposed to show that just because Luffy and crew plan to go somewhere, doesn't mean that's where they're going next, or that they'll get there anytime soon.
They planned to go straight to Fishman Island, but Kuma stepped in and ruined that plan by separating them. While it did benefit them, it just goes to show that there isn't really anything stopping Oda from having Luffy plan and crew plan to go to Zou, and then something happening that causes them to have to do something else. From the way it's looking, exactly that is gonna happen since Big Mom is attacking the Sunny, and there's no Sanji and the weaklings of the crew are gonna fend off a Yonko crew.
I'd like you to tell me how you know Big Mom's crew won't kidnap Sanji's group, and cause the Strawhats to go to a different island, go somewhere other than Zou to get them back?
Also, they didn't plan to go Enies Lobby, they HAD to go Enies Lobby. When they landed on Water 7, they had absolutely no intention of ending up at Enies Lobby. That also shows that what the Strawhats plan, and what they do, can end up being completely different things.
I'd also like for you to tell me how you know that after Zou, it'll be about the Revs? Just because Sabo is here? Luffy encountered Dragon, the LEADER, of the Revs back in Loguetown, and we didn't hear about the Revs again for HUNDREDS of chapters, so just because Sabo is here, doesn't mean the Revs about to dive into the story.
