No GI Joe Crossover
Revolution takes place in the "IDW Continuity", which is the continuity that was started by IDW in 2009 (not the ARAH comics Larry Hama currently writes). Also for all of the Transformers series, the "IDW Transformers Generation 1" continuity, which began in 2005, is now directly connected to GI Joe through the Revolution crossover. GI Joe characters will be appearing directly in many of these crossover title
