Question about Timeline for AQ

Hey,
in the Timeline there are 2 Points for AQ, first the Gates then AQ itself with 1.9 Content.
What exactly is going to be added with the Gates? Everything but the Raid and 1.9. Item Changes?
On Retail, IF i remember correctly Cenarion Hold for example was added with the Nightmare Dragon Patch but i'm not sure what Quests were added with Cenarion Hold and which came later on, but since the Timeline says "Gates of AQ" it makes me wonder if the actual Questchain for the Scepter of Shifting Sands will be added in that "Step" of the Timeline aswell and only the Raids follow a month after?
Maybe, and that is quite possible
, i'm just stupid, in which case you're free to laugh, but it woud be nice if it woud be cleared in the Timeline what exactly will be added with each Step.
Best Regards
Trinat
