I'd like to see another "challeneger to throne", so to speak. Whether internal or external, we haven't seen a serious threat to the UN Spacy, Earth, or the Macross since the original series. Mass destruction, high drama, the future of the human race hanging in the balance. Space fleets racing in from the colonies to save Earth, fight the enemy, whichever whatever. A civil war would be rather interesting, too. We haven't seen that yet. And we still have the Supervision Army which has yet to be heard from...
