I mean it’s just conjecture but
- There’s really nothing left to make of the Warhammer classic world. Just bits and bobs like Chaos Dwarves and Chaos armies. Hardcore fans think that’s cool - are they really going to spend 3 years or whatever to make Chaos Dwarves? I wonder.
- They’re not obligated to do this. I mean they said it however many years ago but they’re not selling these things as being forward compatible, imo.
- Performance on another map 1/3 larger again would be a real obstacle.
- There’s already a Chaos invasion as the major framing device. War 3 would just be, i guess, just more Chaos invasion.
whereas
- Age of Sigmar has mix and match armies. Which would really change up the balance.
- Setting is new. Stupid, but new.
- Medieval Space Marines. They would be the first (as far as i know) to be the video game equivalent to represent Immortals or whatever they’re called.
- Games Workshop would probably prefer they start pushing players away from the Old World setting into the future setting they’ve laid out.
OTOH, maybe a super climactic end of the world War 3 has some appeal, and then they could do Warhammer Age of Sigmar a couple years later.
If they do make War 3 Age of Sigmar i can see a
“final” End of the World scenario for War 2. ring released eventually.
