What's going to happen in Star Wars VII?

If George Lucas can be believed at all, and Anakin Skywalker is truly the main protagonist of all the Star Wars movies, the new Star Wars VII must be about conquering both the light and the dark.

Back in the early 90s, before there were a dozen new Star Wars books a month, I believe this series from Dark Horse Comics came the closest.

If Luke, or Leia, or the progeny of the Skywalker line, whoever it may be, is the "chosen one," then Anakin already tried and failed. That's why I don't like the prequel trilogy that much. It needed to set Anakin up to go to the Dark Side just a little, just a bit to get a tad more power to try to beat some greater evil. He needed to lose, yes. Then he falls to the Dark Side, loses to Kenobi, and becomes Darth Vader.

Luke, in order to beat a stronger evil, such as the reincarnated clone of Emperor Palpatine in this Dark Horse series, Dark Empire. Luke, though, is able to conquer both sides and win, eradicating the evil and beating the Dark Side in the process. That could then be the end of manipulation of the Force by only Force-sensitives. It now goes out to all of us...does "long time ago" ring any bells?

It's supposed to be allegorical. Luke is the Everyman. Now we all have to beat our own Dark Side.
