Honestly, by itself, this posting could mean nothing coming; there’s a chance that Ayaz posted it simply because he loved David Aja’s cover art for this issue. However, interestingly, this particular issue does explore one relevant topic to Wanda, which is her past and legacy. In Issue #4 of Scarlet Witch, it is revealed to Wanda that she was not the first Scarlet Witch, but that it was a title passed down generations thanks to witchcraft. Wanda learns that her mother, Natalya Maximoff, called herself the Scarlet Witch as well
President of Marketing for The Walt Disney Studios, Asad Ayaz, has recently been sharing posters and promotional images having to do with WandaVision. The executive has now cryptically posted the cover of Issue #4 of James Robinson’s Scarlet Witch with no comment

WandaVision might lean far more into witchcraft than some fans may expect, and it could turn out that her powers are the product of witches rather than her Mutant genes
