I wouldn't get my hopes up just yet. Pyro is also the 3rd class to choose from, and incidently the last one left. Valve is known for denying the existence of anything to do with 3.
That's what they all say prior to being exposed to hats. That "pointless crap" is also the reason Valve made 8x more profit last year alone than all others combined, not to mention significantly increased the games longevity. Who wouldn't want to see their own hat/weapon/map added to the game?
