2.1.0 End Game for the Non Raider

[Monkey]

(emphasis mine)

Skettis

The Skyguard, Sha'tari warriors specializing in their command of the skies above Shattrath, have taken the offensive directly to the Arakkoa capital city, Skettis. Perched high in the mountains of Terrokar, and only accessible with use of a flying mount, Skettis holds new and exciting content for the solo or small-group level 70 player. All new quests, 5-person bosses, rare and epic items, and a new type of flying mount await those willing to lend their sword or stave to the battle.

Skettis is, in fact, in the game right now. It's these "Skyguard" blokes who are missing! I hope there are some BE Sha'tari. Half the reason I went scryer with my druid was to get away from the goody-goody Draenei.

Ethereum Prison

Players in good standing with the Consortium will be tasked to deal with the most recent activities of the nefarious Ethereum. With new quests, items, and content for the solo and small-group level 70 player, the Ethereum Prison will be the proving grounds for many aspiring to greatness.

Ogri'la

The Ogre plateau of enlightenment opens to those who prove their worth in Blade's Edge Mountains. Level 70 players will be able to help the Ogres of Ogri'la battle invading forces and engage in new and exciting quests, such as a repeatable and ever popular bombing-run, this time using your own flying mount but with a dangerous twist! Featuring tons of new quests, the Ogri'la faction, 5-person bosses, and rare and epic items, Ogri'la is a place we're hoping all will aspire to enter.

Ethereum Prison and Ogri'la both sound like you'll need to be keyed somehow to access them...
Are these instances? Instanced cities? Or what?

edit: added longer commentary to make more sense.
