Well it looks like T-5 is back on track.
The word is that they will be bringing back Robert Patrick (T2's T-1000).
Only Patrick will play a human who was the template for the killer machine.
Christian Bale will continue to star as John Connor - this new movie focusing more on him, as the fans have wanted.
It is unknown whether Sam Worthington (Marcus) will return.
Meanwhile, Anton Yelchin (Kyle Reese) may or may not be in the film, too.
The story is rumored to concern John going back in time to somehow prepare the militaries of earth's past (our present) to fight Skynet.
I'm not sure how this will play out. I personally wanted to see more Future Wars.
It is said that Terminator 6 will definitely be Future Wars hardcore and have a huge role for Kyle Reese (hopefully Anton Yelchin).
This whole series makes me dizzy from all the time travel.
