You make it sound like a popularity contest, Kraco.
Classic or not is not defined by popularity. Otherwise all (more or less) shallow shounen anime would trump all the rest.

Maybe I´m overestimating "younger" people, but when I started watching anime, I entered as a Pokemon/Dragon Ball-fan. I proceeded to watch Naruto (with Japanese voices and English subtitles). And when the time was ripe, I was looking for the good stuff. Meaning, I turned towards already released classics - and I loved them, despite not having watched them when they were originally released.

And unless I´m a special case (I´m not), new anime-fans will at some point ask for those same classics that I got recommended many years ago. And neither BTOOOM nor Psycho-Pass nor Eureka Seven: AO will be along those.

But to give some perspective: There is one genre of anime that´s kinda experiencing a rise in overall quality, which is romantic/comedy/drama/slice of life, whatever you call it.
