Ya, like I said, it'll probably be scout. Valve has to make money, these updates aren't for pro players (Some are though), their really to get people to buy the game, and make harder classes easier to play.
Before the updates:
Heavy was a sitting duck with no medic.
Pyro was Kenny.
Medic healed...
Now:
Medic can kill almost anyone with blutsaugher.
Pyro is best CQC player.
Heavy can survive without medic.
The soldier and demoman can really take of themselves, not only would a big soldier or demoman buff be pretty useless, but imagine the crying on tf2 forums if their was such a thing for either class?
If you've been a member of a TF2 forum for awhile, it should become quite obvious if those two's unlocks are a big buff, people would just up and quit tf2, something counter-productive to these updates.
In fact, if you've paid attention to Valve's comments about the demoman being 'a little out of whack', but their not going to change anything, it would become perfectly clear their planning on making every class pretty much equal in terms of survivibility.
With all this said though, small buffs, like the heavy sandwich, could help a soldier, esp. if the small updates are a better gun then the shotgun...
Of course, keep in mind, I AM jumping to conclusions, but only because of how the updates have been made.
Valve COULD decide to make the demoman run around with just a bottle, give a scout a gauss gun, and make the soldier run with scissors.
I'm not really expecting that scenario myself
