Only two months after the previous blog update, the TF2 blog has updated, and it's big news:
The scout will have the next update. This is precisely what I predicted. Ignore the fact that I also predicted the spy and the sniper too, the point is that I predicted the scout. Seems like my rule of "least played class is updated" still holds up, after four updates. That's a pretty good record if you ask me.
In an attempt to help the most played class, the Engineer will soon have upgradable teleporters and dispensers. I think the thing I'm most eager to see here is the new design. I guess that makes me a bit of a nerd.
Also, the spy's invisibility will be recharged by picking up ammo. This could be a big deal, but we can't know the effect until we see how much of a recharge it grants. Theoretically, a Spy could be perpetually invisible if he stayed near a fight. This would be worthless, but interesting.
