Oh yes, Arnold Schwarzenegger says "I'll be back" in a new Terminator robot flick titled T-3: Rise of the Machines! The movie will take place sometime in the future as hinted at in the first two movies when skynet becomes self aware and decides the grim fate of humans. James Cameron seems excited to direct this film. This new movie will likely not have Robert Patrick reprising his role as the T-1000 model, but instead we may see an even more powerful female terminator. We probably won't be seeing Linda Hamilton reprising her role as Sarah Conner either. Don't hold your breath, though, production has been pushed back and it looks like this flick won't come out until Summer of 2002. And, with all the people turning down roles for this movie, it may not happen at all. James Cameron may not get to direct the film and if that happens then Arnie's pulling out too! The fate of this movie might be terminated before it's started by the rise of the Hollywood machines.
What and yes, there may even be a Terminator 4. Here's another aritlce about T3 Rumors. Here's another article about Terminator movies. Here's an article from ABC News. Here's some goodies about T3. Here's a goofy mix up between Kirk Cameron and James Cameron. Here's a weird T3 link.
Hasta la vista baby.
