Hi, i just had a look in the next issue of TV TIMES and this is what it stated:

What's next for..... Primeval?

ITV has confirmed that Primeval is being axed after three series, as the broadcaster tightens it's belt due to a decline in advertising revenue. The adventure show, which starred Hannah Spearitt, has been picking up respectful ratings.

I'm sorry guys, but there dosen't seem much hope. :(  So all we can do is keep intact for any other news and just wait patiently.
