The Jurassic Park 2011 line, dubbed "Joe-Rassic 2011" by some fans, was to feature retooled versions of GI Joe figures and vehicles. What is unique about this line though is the fact the dinosaurs featured were going to have entirely new sculpts with as much articulation as the GI Joe repain figures Hasbro was intending on using. The figures would also feature realistic weapons as well as poseable dinosaurs. Unfortunately this line was canceled before it could further see the light of day beyond the prototyping phase. Some of the figures and vehicles were finished. It was rumored, though there is absolutely no source, that this line was meant to be prototyping for Jurassic Park IV.
Due to the nature of this line being canceled, additional information is speculative at best until verified by Hasbro through JPToys if possible.
