-A lot will be unresolved at the end of the episode that will be addressed in Doctor Strange: Multiverse of Madness (remember that originally there was only going to be 2 months between WandaVision and Doctor Strange - but due to COVID it will be a full year) - Nailed it

-Wanda will get her new Scarlet Witch costume - It looks awesome too!

-White Vision will speak and it will be the voice of Ultron (James Spader) - nope

-Wanda's Vision and White Vision will fight - ultimately they'll end up merged and Vision will officially be not dead anymore - I think I get credit it, Vision is back and red vision likely merged some of his conciousness with White Vision when unlocking his memories

-The kids will be kidnapped and Wanda will go searching for them in the future (DS2) - partial credit, not kidnapped, but not gone forever, they were calling to Wanda in the post-credits scene

-We'll see Rambeau fight Hayward with her new powers - yep, saved this kids with her powers

-Woo's missing person will be revealed - I guess the identity didn't matter, it was just someone in the town

-Agatha will end up allied with Wanda and will mentor her going forward -unwitting ally, and Agatha did teach Wanda about runes, I think we'll see more of her in the future

-Doctor Strange cameo - post credit scene perhaps - partial credit, Wanda was doing a Strange by studying while astral projected, and it was Doctor Strange's theme music playing at the time

-Hex will be expanded just briefly to cover the whole Earth and will be the origin of mutants - I knew it was a long shot, guess the introduction of mutants will be later
