It's only a matter of time before things start becomming stale, it's ineviable for all franchises. Macross is no exeption, a few series down the road, unless Kawamori decides to totaly blind side us (music plays a small role, not much of a love triangle, UN Spacy blows the hell out of someone with sheer military might, etc...) people are going to start bitching that it's getting stale as well. Honestly I will start complaining about repetativeness if the next few Macross series (provided there are more) center around, a singer, a love triangle, music, and some foe indefeatable by conventional means.
