There was a JP line slated for release in 2010, following the TRU exclusive line from 2009 that was all JPIII repaints. The line has hit some snags since then and there is now a possibility we may be seeing the new line in 2012 some time, but Hasbro is being very tight lipped about the whole thing right now. They've claimed their systems show the line as cancelled, but a lot more prototype figures have shown up in the last few days, so as of right now, only time seems like it's gonna tell.
I seriously think we should start a Jurassic Park toyline thread on this site, the only good JP toy site is JPToys and their based in Europe, we should have a thread for Canadian fans to discuss JP figures. At least, in my opinion.
