Stormcast vs Skaven.
I can't see a starter set without Stormcast. Love or hate them, they are the face of AoS.
I can see cities getting a 2nd wave, cultist stuff mainly.
I think and hope quite a few factions will get 2nd waves next year.
GW have been releasing either new armies or doing redesigns and giving us new toys but it almost always feels like there is more to come.
Kruleboyz, cities, deepkin , fyreslayers, kharadron.
Even 40k has it, the eldar redesign wasn't a full release and there must be more squats coming.
I think 2024 will be a good year and I can't wait to see what they come up with.
