Any news/rumors about the next class(es) to be updated?

The Character Setup GUI in-game suggests that each class will be updated with achievements and unlocks much like the medic. However, I haven't heard any official news or rumors about which classes are next in line (then again I haven't looked very hard).

Tell me what you know tribal buddies...

Rumor has it the pyro may be the next in line.

(5/13/08) Doug Lombardi interview on TF2 updates and more...

I have heard "rumors" too, but this is Valve. They are one of the best companies out there for keeping their secrets, so it's not even worth speculating.

I hope they update spy before sniper. That will make the sniper update a lot more tolerable if spys are updated by then.

engineer upgrade will probably be a pyro type turret.

Some ass over at 2fort forums asked if they can put up a artillery class, almost like the mortar man in RTCW:ET so u can spam on 2 Fort...lol the last thing TF@ needs is someone lobbing shells over the wall on 2 Fort.
