I always hoped for some decent Jurassic park games to come out so lets hope this will be good.
About Trespasser:
I loved trespasser completed it a few times, there are a few mods that have been made for it, check out "trescom" they have been working on improving that game since it came out and have fan made levels and a few other patches to make it a lot better.
Although most people could not get past the serious buggy nature of it, i still enjoyed playing it, the biggest problem was the publisher forcing them to release the game when it was something like 25% completed.
Shame they wont release the source code greedy people suck.
I also remember hardwar coming out at around the same time, there is also a bunch of patches and remakes in progress for that too, captain zedos IIRC was one of the main sites.
