Terminator Salvation (2009)

Other mistake: When Marcus, Kyle and Star are at the petrol station, a flying HK and the giant Harvester robot are able to appear just outside without making any kind of sound. In every other scene of the Harvester and the HKs however, they both make an incredible amount of noise. (00:37:40)

John Connor: I knew it. I knew it was coming. But this is not the future my mother warned me about. And in this future, I don't know if we can win this war. This is John Connor.

Trivia: Reese's introduction isn't the only thing that stays the same about the character between movies. Here he uses his preferred weapon - a sawed-off shotgun. Marcus isn't keen on having a gun aimed at him though, so he snatches it out of Reese's hands, then teaches him a trick to keep that from happening - fashioning a safety strap. Reese puts that same trick to use after he steals a police shotgun in The Terminator. (00:49:55 - 01:49:58)

Question: The ending of this film seems rather vague on the actual outcome of destroying Skynet's HQ. Does that mean the humans have won the war or is Skynet still a threat? The ending of Terminator 3 would suggest the latter since there it was confirmed that Skynet is capable of moving from transferring itself from one installation to another when needed, yet here everyone seems to believe they accomplished a significant victory. So which is it?
