IMO this whole time travel, prequel, sequel mess is just another attempt to make this storyline more marketable and allows the future writers, directors, etc more power to continue this story as long as they can milk it. Confusion is not story telling, but that looks like how they are going to pull along fans til the end of the third pic I bet to explain everything. You wanna throw a monkey wrench in? Make everyone find out at the end of this trilogy that John Connor is a Termninator. Couldnt he have been replaced at some point once he reaches adult age? Or even a Terminator that can grow, learn, age, feel pain and fool all that surround it.
