Prestige for a knife and fancy icon, sure- ok, that might be nifty, though you know there are going to be people abusing perk-training for it. Since prestige doesn't change the gameplay itself, I see nothing terribly wrong with it.
KF1-style DLC Character pack? ehh... I'm not so fond of this idea given my bad experiences with DLC Characters in in KF1 not working properly. but, whatever- it's fine, I'm sure a number of people will enjoy Mrs.Foster regardless of how it's implemented- and that's a good thing.
Completely re-balance the weapon system by changing weight and damage and adding 'upgrades' No... This is not okay in my book. It seems like a really bad idea that will only end poorly. I'm really worried about this, and I'm not the only one. Here are some quotes from friends of mine, some of whom are also fairly prominent in the community- with their reactions to this particular facet of the announcement:
That Heavy Goat made a great post on the subreddit here that accurately describes a number of my views on this:

"Tbh, I'm curious what makes them think 'nerfing a gun so you need to work harder to make it normal' = 'upgrading'. It's like 'we have a bigger size of pizza, here's a even smaller size one, and you can pay more to make it bigger!!' †-SteveM

"I'm actually sad about the whole ordeal. This feels like a legitimate funeral." - Stohgee
"That sounds dumb, I'll reserve an actual judgement though til after I play it" - Dark Darkington
"they're high, it's 4/20- they have to be high" - pooploop
"they gone full retard" - level
"there's 0 chance the weapon upgrade system isn't going to be broken" - Amathy
"I have no idea how this game is going to be balanced if you can upgrade past current stats"
"anyways, seems like TW is ready to go full retard again. We'll see how it turns out for them this time, ggs" - Kore
"the weapon upgrade system looks like rip game balance" - Koh
So TWI, I know the opinions of long-time players probably don't mean too much to you, since the game is balanced around the vast majority rather than outliers like myself. (Though I do wonder just how much of your MTX comes from long-time HoE and CD players buying up keys and precious items compared to the rest of the user-base.) But you've got a lot of players worried about this. You'll be messing with balance in a way that could easily turn out disastrous and ultimately drive away a portion of your playerbase that has done nothing but promote your game for you free of charge while assisting with player retention. (A lot of us wouldn't still be playing this game after all the nerfs to vanilla HoE without controlled difficulty and friends to play it with).
I urge you to be very careful in considering how these changes to weapons will affect current balance, and I'd strongly recommend ditching the idea entirely- or at the very least, limiting it to endless and only endless, and leaving survival alone.
