Rio Grande Games will release a new large expansion for Donald X. Vaccarino’s award-winning Dominion card game in Spring 2015.
 
"We are now working on a new (large box with 400 cards) expansion we expect to have available in the spring (2015)," Rio Grande’s Jay Tummelson said in a recent Board Game Geek forum post.
 
"We expect then to be able to release the game in late spring - dare I say March or April or May.  We will send more information as we have it," Tummelson also said in another post.
 
As for future Dominion plans, he also stated, "We may replace the original Treasure and Victory cards (already available separately) in the base set and/or Intrigue at some point, and are also looking at offering a set of the metal tokens (the Treasure and Victory tokens) later in 2015."
 
The original Dominion card game, released in 2008, won the 2009 Spiel des Jahres Game of the Year award, the 2009 Origins Award for Best Card Game, and a Mensa Award (see "Rio Grandes 'Dominion' Wins Mensa Award").  The popular card game last appeared on the Top 10 Card/Dice Games chart in Fall 2013 (see "Top 10 Card/Dice Games--Fall 2013").

Rio Grande recently announced several other Q4 and 2015 releases (see “'Mogul,' 'Elfenland' Reprint, 'Bohnanza' Expansions”).
