There is no patch for the 2013 (2012 cards) game as of 3/19/2013, but I'm sure one will come along soon enough.

The latest patch from Strat is for the 2012 game (2011 cards). You can get it from the Strat-o-Matic Patch Page.

Previous year's patches are also there, but there's really no reason you need them if you update to the current patch.
