That's because GW fans are freaking stubborn as all hell. I did a 15 year anniversary panel for GW and got nearly a full room. It was super surprising, especially since most of the people there were younger than I was. Just proves that its a classic (even if the butt hurt male gundam fans whine about every little detail ever).
Also, older series that can hold up against new ones (GW, Cowboy Bebop, Trigun, DBZ, Eva, Sailor Moon, Inuyasha, etc) were such gateway anime for Americans that its hard for us to let go of that history. I mean almost every fan I know that got into anime between '95 - '05 started with one of those, watching on Cartoon Network. If they started with something else, it was a copy of a copy of a copy of a bootleg fan sub on VHS that they got from their friend's cousin's internet friend from Japan or something.
Now there's just so much saturation everywhere, and more and more comes over to the US every year so not everyone is watching the same 3 shows that year.
