Well, sorrow, from what I've read thus far (next to nothing), if there is to be a T4, by the same director as T3, the storyline will apparently be based in the future, the first 5 years of "the war",...if that WERE to be the case, it should be full of the metal dudes, y'know, early stages of development and all...

well if that is the case cheeba there is no need to put an arnie replacement in the movie right? witch makes me a semi satisfied man.
