Schwarzenegger once again makes good on his promise to be "back"

In case you haven’t been keeping up with the twists and turns of the Terminator reboot, Terminator Genisys, this new teaser should help clear things up.

“Everything’s changed,” new Sarah Connor – Emilia Clarke – intones solemnly in the trailer, because this isn’t your mom and dad’s Terminator.

This is a new, 2015 Terminator, with electronic dance music pulsing in the teaser and a terrifying new cyborg chasing after the Connors.

Also, oh yeah, old Arnold Schwarzenegger is going to fight young Arnold at some point.

We’re still not 100% sure how the time travel plot’s wrinkles will be altered in the new film, but from the trailer, it’s clear that Schwarzenegger’s T-800 has been around for awhile by the time the movie takes place. It also appears he will be confronting a “new model” version of himself, which will come into being via some impressive computer effects.

Also, things will explode.

How excited are you? At this point, not even Stephen Hawking can dampen our excitement.
