Yes, you saw the teaser trailer to the teaser trailer, now check out the full teaser trailer to Termintor: Genisys, leaked early in a hidden post on the official facebook page of the film (and the youtube version followed quickly, and now replaces it for higher quality).
We think that's right, anyway.
The still-questionably-titled Terminator Genisys opens July 1, 2015. As the trailer reveals, it is a soft reboot of the original film, starting with the same general impetus - Kyle Reece goes back in time to save Sarah Connor. When he arrives, he finds she's already been saved, and is already fighting, thanks to the help of an old reprogrammed Terminator bot. This is going to get even more confusing - watch the trailer and start trying to sort out the timelines for yourself.
