Quickest way to power level to 70

[BorisDaBlade]

... Umm main story, same as it was for HW just burn the story will be 70 day 1 maybe 2.

So, am I to understand that everything is in place in 4.0 to get to 70, like all the 61-69 dungeons, or do we just get a couple of msq dungeons per patch?

I know the job quests are most likely there.
