Is Darth Vader alive in “Star Wars: The Force Awakens”?

So does Darth Vader come back to life for the new Star Wars trilogy? In the new trailer, Luke’s voiceover uses the present tense when describing his father. At first I just thought that since that passage is taken from Return of the Jedi, that it didn’t mean anything. But that LAST line, “and so do you”, indicates that the passage may actually be taken from the NEW movie. Which means that Luke considers Vader to still be alive. And then there’s that melted helmet. Why bring the helmet into this if Vader doesn’t actually show up? At the moment I’m thinking Vader DOES come back to life in Star Wars: The Force Awakens.

And that rocks.

Star Wars rocks.
