Great, now the soldier can run around almost as fast as the scout with his equalizer AND he can suck the life out of enemies with rockets. The only downfall? 1 less rocket in your clip.
Pyro has a pretty suck flamethrower unless you use axetinguisher.
Scout has milk and fish. :D
Spy's new item is interesting. No disguising, but a backstab will instantly disguise you as the person you killed, and the kill is silent. I can see it being useful in certain situations, but I think I would prefer the original knife.
