Secret Fifth Class of the EPF?

In today's newspaper Rookie mentioned something interesting during his interview with Jet Pack Guy (aka JPG for short).

If you take a look at the EPF phone under Gear you'll see that not including normal agents there are four other special classes: Tactical, Comm, Tech, and Stealth.

Rookie hinted at another secret class of agents and I highly doubt that was a mistake. I'm thinking Club Penguin might release a new EPF class sometime in the future.
