I don't see why looking forward to something must inevitably result in being disappointed that it isn't (exactly) what you imagined. Since you're aware of the dynamic, that leaves you in a much better position to take charge.
I would suppose, offhand, that the "hype-Hype-HYPE-disappointment" conga line is something you grow out, deliberately train yourself out of, or both. I remember, as recently as 2.0's release (over six years ago), still being somewhat susceptible to it. After that, not so much. Time feels like it flies by so quickly that trying to keep up with all the shiny new stuff is without purpose. I'm behind on everything as it is, and those new things will just be part of the backlog in a few blinks. "Newness" is a sheen that evaporates so quickly that it's hard to get excited about it anymore. It's basically just cynical capitalist culture wanting me to be excited, anyway. (Social media buzz, for example -- free advertisements!) Taking things at my own pace and exploring the vast and ever-expanding library of human creativity -- nearly all of which is "new" to me, regardless of when it came out -- is much more rewarding than impatiently looking toward the future for the next novelty to promptly gobble up and shit out.
(Not saying that those impatient with Anno are going to treat 3+1 Repeat Sign as cinematic junk food, but the "urgh, hurry it up and give it to me, asshole! you're losing points by making me wait!" attitude almost certainly has something to do with being nursed into an addict mind set by the mass media market, analogous to the food industry's "put refined sugar in fucking everything and watch the money roll in" approach.)
