Finally!

First off, Waldron had written some great stuff. Loki and Multiverse of Madness, not to mention the upcoming Doomsday and Secret Wars stories. So this is exciting.

Second,

While the character didn’t have many run-ins with some of the main figures of the current or past MCU, he did have some battles with the Skrulls, who have big parts in recent Marvel projects including Captain Marvel and the limited series Secret Invasion.

I have to guess that'll be changed long term. In fact I wouldn't be surprised if we got a big Skrulls reboot.

And thirdly, I feel like Nova had a great setup after Infinity War. Thanos destroys Xandar off screen. We could have seen his origin and Thanos wrecking shit. I hope we still get something like that.

The Kree / Skrull war was a huge plotline in Avengers #89 to 97. Would make a good film.

The destruction of the Nova Corp back in GOTG would be a good place to start and follow the Nova run that leads in to Annihilation, etc.

It’s been a while since I read it but basically the core gets destroyed (in a different way that I can’t remember) and Richard Ryder gets the full power of the Nova force and goes on his own adventures, eventually trying to rebuild the Nova Corp
