I'm always a bit torn when we get info like this. It's sort of spoilery, except it doesn't actually say anything about the plot or even that the Big Mom/Luffy conflict will be resolved before we see Wano.. But still, we're at such a point that any info about how quickly the plot might progress can be too big of a reveal to some.
On the other hand, I would have loved to read info like that during, say, Dressrosa which just seemed to drag on forever and there seemed to be no end in sight..

... I think the (recent) movies are the only exception where they allow a scene or two that could be considered more gratuitous, but I don't really have a problem with it since they're movies and only seldom provide this sort of thing for some fans to "make up for it" in some way, like a bonus of some sort.
