I think Oda will preserve the M3 dynamic for the core crew. What was shown or established since the start (East Blue) will persist. Luffy = Zoro > Sanji. 6 in Strength for both Luffy and Zoro and 5 in Strength for Sanji (as per one of the earliest databooks).
I disagree, and think there will be a gap between Luffy/Zoro as well, not matter how low.
But anyway, as long as you think the gap between Zoro/Sanji at EoS won't be high enough to the point Sanji gets low or mid diff'd, that's respectable.
They will be close in power, the big gap that exists now will become narrower

As per the manga instead of a databooks of early one piece which Oda wouldn't care a shit about and strength could be referring to physical strength not battle power.
So much out of context here.
- Doriki measures physical power. When Lucci/Jabra were physical combatants, while Kaku was a swordsman. Plus, Kaku didn't have his DF back then (we know zoan DFs have an impact on base as well). Lucci/Kaku dynamics was established back then (which is still active!) for a reason
- Lucci was actually a bit stronger than Luffy, and Luffy needed extreme diff + PoF to beat him, was KO for days afterwards. Zoro and Sanji high diff'd their opponents, had more energy to spare.
Same manga had Luffy/Zoro fight in wiskey peak and fight to an even. I can pull up more Luffy/Zoro portrayals than you can pull up Zoro/Sanji portrayals.
We can all cherry pick what we want to push agendas, but when overall picture is looked at unbiased, it establishes portrayal/dynamics between Luffy/Zoro (captain/partner), Zoro/Sanji (two strongest underlings), Luffy/Zoro/Sanji (monster trio)
