The folks over at Jurassic Island posted a very interesting but unconfirmed article today on JP4's production. If true, it looks as if Hasbro may have had a 10th anniversary toy line planned all along. Here's that blurb along with a tid bit on what to expect with the JP4 toy line:

"With JPIV, we can expect lots of merchandise including, action figures. Although it seems only natural that Hasbro (who designed the JPIII line for 2001) would take the wheel, but the toy company who had planned to release a special Jurassic Park 10 year toyline and than dropped it has dropped the JP license for the time, perhaps meaning that a new toy company will take over."

So there you have it. Other than the mention of what could've been a 10th anniversary line, it's also interesting to note the mention of "lots of merchandise including, action figures" for JP4. That's not to say I wasn't expecting a JP4 toy line but with Hasbro's past of dropping the JP license (not to mention entire production lines) - anything's possible. Once again though, this article has not been confirmed so you'll probably want to take it with a grain of salt.
