I honestly don't understand why air a series that isn't done. Why not finish it up and make it perfect before releasing it? Eureka Seven, as a title, already was popular, and had a great potential for investments over time. They could create a gloriously brilliant masterpiece successor, a great sequel, if only they took the time to plan everything out.
I'm debating with myself on whether I'm mentally satisfied with Psalms of Planets' ending for the whole story, or accept Astral Ocean as a legit continuation for the plot.
