Pretty much. Seeing as though the advisers are being given companion level exposure and we know that at least one of them is romanceable, I can't seem them not having a much more prominent presence within the game than what we saw in Awakening. But how far that goes is still way up in the air.
A lot of people, myself included, hope and are tentatively assuming that they will be temporary companions at some point. There's a good chance they'll have loyalty missions like companions do in all the recent BioWare games, so those would be at least one point where it would be plausible for them to join your group for a time.
Not sure if you saw this, but we got some clarification today and they won't be temp companions it seems.

Right. They have different roles from followers, but equally as important. You'll see them a lot!

@HulegaardBooks I see. Can you answer if the romances are equal to the reg party member ones as far as content?
David Hulegaard ‏@HulegaardBooks 2h
@user yes.

well, advisors don't travel with you, but they're responsible for other elements within the Inquisition.
David Hulegaard ‏@HulegaardBooks 2h
@user you'll see them, you just can't take them with you in your party.
User 2h
@HulegaardBooks Is there a good amount of interactions with them?
David Hulegaard ‏@HulegaardBooks 2h
@user absolutely!

Sounds pretty great to me though. I'm looking forward to Cullen's romance, so I'm happy to see them on equal footing to companions.
