-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)
-Wanda will get her new Scarlet Witch costume
-White Vision will speak and it will be the voice of Ultron (James Spader)
-Wanda's Vision and White Vision will fight - ultimately they'll end up merged and Vision will officially be not dead anymore
-The kids will be kidnapped and Wanda will go searching for them in the future (DS2)
-We'll see Rambeau fight Hayward with her new powers
-Woo's missing person will be revealed
-Agatha will end up allied with Wanda and will mentor her going forward
-Doctor Strange cameo - post credit scene perhaps
-Hex will be expanded just briefly to cover the whole Earth and will be the origin of mutants

We'll see how well I did tomorrow.
