It is possible, post-CoTF, to return to "smaller cycle" expansion if the pricing structure is changed. I recall the lowered price for Legacy of Ykesha ($21.99) seemed comfortable for many and a positive test for digital download.* [*Not factoring inflation. Discounts may be limited due to the All-in-One nature of purchasing expansions]. If a cushion is required in the future, I suspect a semi-annual release (3-5 zones, spells/AA) at a discount (ala carte) might be an appealing option.
