Yes, what we can expect for AoS right now is:
May: DoK and NH battletomes (mid to end of month)
June: Summer BattleBox for the expected Sylvaneth vs Skaven
July: New GHB 2022
August: Nothing
September: Sylvaneth and Skaven battletomes
So we have the period of October, November where we might have another two battletomes, as the finals of November and all the December is focused in Christmas deals.
