So I've just gone through the new process. Yes, it requires GE/Nexus pax to speak with an agent. My "interview" this morning took about 10 seconds and I was on my way. Granted, there was no one ahead of me in the queue, but the GE/Nexus lane feeds you right to the front of the other lines. So unless there are a million people waiting ahead of you, it shouldn't take all that long to get through to an agent.

The rest of the process was pretty smooth. Security was deserted but looks like it could get crowded at peak travel times. No worse than the old system, probably a little better the rest of the time.
