Are they seriously calling adding a "new" gamemode that's already been playable for years on community servers (because it's a community mod) and a few other community-made maps into official servers a "Major Update"? This is not a "Major Update", but actually a "Major Cope" (10/10/23 note: did I actually write that?) from Eric Smith (the only person officially working at Valve that's maintaining Team Fortress 2 currently) to gaslight the playerbase into thinking this game is still being kept alive by Valve (The Company).
When are we getting new weapons? When are they going to nerf the diamondback, the spy's kunai, the crossbow (or maybe buff all the other medic primaries except the crossbow), and various other weapons? When are they going to fix the Revolver animations? When are they going to remove (or disable by default for servers) the game design failure that was random crits?

Even the official implementation of the VS. Saxton Hale gamemode isn't up to Valve's signature polish, as it's a community mod. Meaning Valve did nothing but add the maps some community members made to the casual map pool. And while I liked it in community server mod form back in the day because you knew it was a COMMUNITY MOD, adding it officially for all players to play takes a bit more than the modding community to do that.
- It doesn't use the known official voice actors for the gamemode's new voicelines (They could use the actor from expiration date or whatever for the soldier)
- Saxton Hale's player icon for the HUD uses the Heavy's icon
- Playing this gamemode doesn't add experience points to your casual rank level

I've heard rumors that Valve is getting more than one person to work on Team Fortress 2 again, but those are just rumors, so you never know.
