WandaVision

Nick Fury sent a Skrull to Monica, so that will probably be a Captain Marvel 2 tie in. Wanda reading the Darkhold at the end will probably end up being the Doctor Strange 2 tie in, because the Darkhold is never good news. Agents of SHIELD had Ghostrider basically "get rid of it", but then it showed up in that Cloak&Dagger show also. The book does corrupt those who use it, so that will definitely be a concern.

I wonder if they'll end up using it to explain mutants. In her effort to bring her kids back, she ends up creating mutants on the planet and then you've got X-Men.

Anyways, was kinda disappointing to not see lots of fan theories came to fruition

When vision touched vanilla vision it's as if he taught a man how to fuck, and a way he went to raise hell. Where vanilla vision go??

Most of the fan theories that were direct comic book plotlines do still appear to be valid, imo, just moving into Dr Strange 2, especially with the post credits scene.

Agatha is still around to teach Wanda, should she require it.
The Nexus of Realities looking basement is still under Ralph Boner's house, which is presumably where Agnes was sent, and was shown to us in real world aspect ratio, not TV show, so it is presumably real and in play
The Darkhold is in her possession, and we hear her children calling for her while she is Astral Projecting. So the comic plotline of them being real but using shards of Mephisto's soul is still in play as well (or her being corrupted by it/him, since thats what the book does).
It also makes me wonder if the Darkhold plays into Dr. Strange 2, if we will get a Elizabeth Hurley cameo in it as Morgan Le Fay

All in all, the show was primarily about Wanda dealing with her grief and retconning her into a more powerful version of herself than was shown during the Avengers movies (where she was already nearly powerful enough to 1v1 Thanos) and sowing a lot of seeds for the next few movies.

Also, I hope the witness protection guy Jimmy Woo was looking for was Paul Rudd and we get a visual gag of him transforming through the timeframes quickly at the start of Antman 3, since that ended up being an unimportant mcguffin.

Only thing I was hoping for was a Dr. Strange cameo. It didn't make sense to me how she realized how powerful she is, it's magic, and she didn't make a beeline to Bleeker Street to see another Avenger who's title is "Sorcerer Supreme."

The only thing that really bugged me was White Vision trying to crush Wanda's head. First off that would have been instant pulp, second, why would WVision not use his powers to stick his hand inside her head and materialize it in there. No but really he was sent in there to kill Wanda, not fight fake Vision, but it seems like he forgot that or something.
