That isn't going to change anytime soon. Higher voices= cuter. And cute sells in Japan, or at the very least, is far more acceptable than here in the U.S. Which ones do that? Most of the time (at least from what I've seen), geeks/fanboys in anime are of the stereotypical "obese, labored breathing, glasses, perverted, pimply, hermit" variety that I wish companies would stop using, because it's a lazy generalization and takes no effort to write.
Unless that's not what you were referring to and I'm just mistaken.
