To that point, I believe it's possible to buy spend futures now in cloud costs and if you're doing that then technically it is possible to predict Amazon's pricing roadmap. I know for sure if Amazon themselves didn't (they do) third parties would (they do, DoIT is an example of one I know that does this but there are quite a few of these compute resellers out there).

But sometimes people are not near enough the spend or product support level where it makes sense to do that. I would gander, though, if you're running cloud cost tooling you probably are one of those people.
