Jurassic Park 2011
Shortly after the release of JP2009, rumor had it another line would be released in 2010. Not long after that pictures showed up of retooled figures that originally came from the GI-Joe toy lines, with the unmistakable markings of JP and INGEN. In 2012 new dinosaur sculpts also started showing up. Originally meant for 2010, this line was rescheduled for 2011 and terminated soon after that. No name or logo, or a list of the figures it contained have been uncovered yet. It has been speculated that this entire line has been cancelled because there is no JPIV movie to support it's release, the fact that the JP2009 line didn't sell well and because Hasbro's licence for the Jurassic Park brand expired in 2011.
Interestingly, after being canned for Jurassic Park, a line called Dino Hunters Adventure Team was scheduled as a GI-Joe line. This line was also cancelled, but it would have featured the same figures as the JP2011 line. In late 2012 a piece of artwork featuring an Allosaurus and a human was found with the logo's of GI-Joe and Hasbro on it, it's likely part of the cancelled GI-Joe Dino Hunters Adventure Team line. It's the closest thing to JP2011 concept art that was found.
On a side-comment: this line wasn't the only line planned for 2011 and cancelled. A second 'Jurassic Park Junior' line was also supposed to be released, which also got cancelled. It is believed those two lines were separate, because of the different age groups targeted with the toys, but it's possible 'JP Junior 2' was actually part of this line.
