I mean it is the safest option for Blizzard, there's no one else that is as devoted to Blizzard as them.
Preach refuses to play Marketing for them which is fair enough considering everything.
There's just no one else available that would play by Blizzards' crazy PR Teams ruleset.
Then again honestly I never expected we would be in the position where we wouldn't have preorders available and we're stuck with this black hole waiting period with small scraps of new info being a possibility with each new interview but mostly its just going over the same stuff and the datamining being the main course in June.
