As Arnold Schwarzenegger says, they’re basically going to just “move away” from the timeline established in Terminator 3, Terminator: Salvation and Terminator: Genisys.
These new comments Arnold Schwarzenegger made to Business Insider offer a little more evidence that this Terminator movie is headed in the right direction.
James Cameron and Tim Miller previously stated that Terminator 6 is going to ignore everything that happened in the franchise beyond T2.
If this first new movie goes well, Tim Miller and James Cameron have plans laid out for an entire Terminator trilogy.
