With all of the hype around a Diablo 4 reveal at BlizzCon, Blizzard squashed the rumor with their Blog Post
. They said that they know what all of the Diablo fans are hoping for but they said they are not ready to release information until the time is right. They did state that they will have some Diablo information to share, but not the information everyone was hoping for. Blizzard also stated that "Good things come to those who wait." "But evil things often take longer."
I guess we will just have to continue the speculation. Who knows?
