Its not confirmed?
Sorry, but you kinda trigger me. You got 6K posts here and you don't even look up before you comment(should be more of your own interest for the community you are taking part of):
"Currently, in Patch 7.1.5, your chance to receive a Legendary is based on the total number of Legendaries you’ve already gotten. In Patch 7.2, we’re changing that algorithm to only count Legendaries with bonuses that apply to your spec. So, if you’re a Fire Mage with the Pyroblast bracers and Scorch belt, you’ll have a significantly higher chance to receive a Legendary when your loot specialization is set to Frost than you do currently."

Given mutliple sources, the first 2 drops are very likely within a week or 2. It you have 3 specs, you can take out 4 of the common legendaries(it can obviously also drop as spec legendary and unusable on your main spec).
I answered my own question.
