If they are doing more of the original animated show, then why not this and Evolution, too?

I really, really want to see how Jean feels about Logan in charge, and how they will put a stop to Apocalypse and Mr. Sinister.

In addition, seeing Evolution's version of "The Dark Phoenix" saga would be really cool and epic indeed! It was foreshadowed in "Power Surge" and foreseen by Charles, after all. And having Havoc on the team with his elder brother Cyclops.
