Dungeon distribution in Heavensward

[Balipu]

At the start of Heavensward we get 8 new dungeons at all.

That includes the story finale, like Castrum in ARR and 2 or 3 Lvl 60 Dungeons to gather tomes.

So for leveling there will be 3 to 4 dungeons.

Actually, they already announced that there will be 4 compulsory dungeons (for the MSQ) and 4 optional dungeons in HS.

Wow, I totally missed there. When were these said?
