A few days ago Collider uploaded an interview with WandaVision Director Matt Shakman. Overall, the interview is interesting even though that Matt is very good not telling any secrets. One question asked regarding a prior post here, is whether there might be a second season with WandaVision. The answer is that he actually don’t know but we do know that WandaVision will be tied in directly with Doctor Strange 2. With this knowledge, we still say that WandaVision has no intentions to become a second season.
Erik Voss and New Rockstars are mentioning in a video about the WandaVision commercials (video also below) and says that the “sitcom commercial breaks” represents Wandas past trauma. That also makes us believe that this really is a one-season series.
