Where do you think Macross can go next after the second Delta movie hits theaters? What can Shoji Kawamori even tackle in a future story? I mean the entire question why music carries such power has been answered in full thanks to the fold receptor concept tying everything we previously knew, and the Protoculture will almost certainly remain a complete mystery.
For me personally, I'd like the next protagonists to be complete music haters, for the story to feel far more inclined towards the mecha like how Delta leaned towards the idol side. The music naturally would need to be there, but I'd rather another SDF arrangement, where music becomes important roughly halfway through the series rather than from the start like 7, Frontier and Delta were. Preferably do something like a major "opening up" arc where the protagonist realizes his bullheadedness towards song. Adress the question of the New UN and the growing corruption. If it is in a reasonable timespan, bring back Berger and Epsilon. I want that fella's motivations cleared up beyond the usual "war brings profit" stuff I've seen all too many times in fiction. Like why is he even interested in Protoculture stuff anyways?
