Anduin Wrynn Joining Heroes of the Storm?

A tweet from Blizzard presumably teases the next hero coming to Heroes of the Storm. This is widely thought to be Anduin Wrynn, the son of Varian Wrynn, who is already a playable character in Blizzard's MOBA. This is not confirmed, so there's no word on when the new character will be joining the Nexus. does warn of downtime for scheduled maintenance tomorrow, so it's possible Anduin may come to the PTR at that time. Word is: "We will be performing scheduled maintenance beginning on Tuesday, April 23rd, 7:00 AM (PDT) and we expect the service to be available again at approximately 10:00 AM (PDT).
