Spring 2007 and Spring 2011 had preview tins featuring the starter pokemon.
Fall 2007 and Fall 2011 had the final evolution of the starter pokemon
Spring 2008 and Spring 2012 had the mascots of the video games and another pokemon, namely Darkrai and Kyurem.
Fall 2008 had Mewtwo and Rhyperior, both being from Legends Awakened for wave 1, and Heatran and Regigigas from Stormfront for wave 2.
I predict that Fall 2012 will follow suit, and rather than having 3 tins, there would be 4 instead, and all 4 would have dragon cards. Wave 1 would feature Rayquaza EX and Giratina EX, and Wave 2 would feature Black Kyurem EX and White Kyurem EX. It only makes sense that way, as I couldn't see it any other way.
