That's still just hype atm, so I don't think buying into it would be a wise idea when you'd get equally disappointed if it ends up unable to deliver. The same could be said of Whole Cake Island, after all.
I agree it does present far more promise than the previous Part 2 Arcs, though I imagine it will still contain some of the series' major pitfalls when considering what we've been given in it's early stages. I wouldn't say it's impact on the story as a whole would be capable of holding the arc up, considering the same point can be made for Skypiea.
