I am a long-time player of 《Warhammer：Vermintide 2》, with a total game time of 3600 hours. We Chinese players need 《Warhammer：Vermintide 3》, and we hope that the new generation of games can be played and streamed in China without being banned by the Ministry of Culture (which would greatly reduce promotion).
Not any time soon.
What does that entail ?
Vermintide 2 is banned on all live streaming platforms in China, resulting in a lack of game promotion and consequently a significant loss of players
Is Darktide also banned ?
I really like Vermintide 2 because its action design is excellent
Darktide was not banned, as China later relaxed its regulations. However, many years ago, Vermintide 2 fell victim to those regulations
Wouldn’t there be process to request it being unbanned ?
Anyway, as said before, not any time soon 
I was also hoping for Vermintide 3, but from this statement it’s become clear that it’s not coming anytime soon.
If that’s the case, then the game currently being developed in UE5 is either Age of Sigmartide, as rumored, or an original IP from Fatshark.
Is it possible that they’re moving away from Warhammer and developing their own original game instead?
We do not know if their next project is on UE5, the job posting might indicate UE5 as an onboarding Engine (Bitsquid/Stingray being quite rarer), no rumours about their next game exist atm with any substantial basis.
It is quite likely that it’ll be years before we start hearing about FS’s next project.
When’s “The old world” relauch for GW? Maybe a launch of VT might be coincide with that.
Already has, and tbh, timing a VT3 with an Old World release would be quite weird, as Skaven aren’t a sold army afaik (and playable, they don’t get updated rules for it).
As well as Old World happening about 200-ish years before the VT1 start, so maybe Kerillian and Bardin would be alive, but not Kruber, Sienna nor Saltzpyre.
Tb, the best “plan” for a Vermintide 3 would be to set it in Age of Sigmar, as it could let them restart the characters while keeping the VA and having certain voice lines refer to their past lives through that whole Soulbound stuff.
I know that I come late but a new Warhammer Fantasy tide game could work in the Old World setting. It would be with new characters but then we could focus on an enemy like the Greenskins, instead of Skaven and Chaos?
Otherwise a game with specific Skaven as the main foe might be hard, although I would argue that Chaos has kind of overtaken the Skaven as the main foe in Vermintide 2, but there are more foes that can be fought beyond Ratmen and Nurglitch Chaos.
