Are you already planning an expansion after Adventures?
If there will be an other expansion, will it have some of the new things from Adventures as well (like events)?
You're not going to get real information, so have some fake:
Expansion 10: Modern Times - introduces a board
Expansion 11: Borders - introduces Team play and player abilities
Expansion 12: The catapult - introduces pantomiming, singing and shooting meeples at the supply
Expansion 13: Legacy - A treasure chest with Vp and coin tokens, Potion costs and the good old team cards from "Borders"
Expansion 14: Secrets - Co-created by Klaus Teuber, introduces player elimination, dice and ressources
Expansion 15: Ultimate - Another treasure chest for Dominion's 40th birthday
That's all planned for now.
