My particular take on the whole shebang is that, "This is, after all, his creation, and he should be allowed to do what he wants with it." If that means Han Solo never shot first, then so be it. But he did. Shoot first, George. Mark my words. I was there. I saw it. In theatres. Back in 1977. Han Solo shot first. Shot Greedo dead in his chair. And it made thematic, dramatic, and narrative sense. What you did? That flick of his head to miss being shot? That's just plain stupid. But I forgive you for it.
However, this morning The Verge reports that Lucas is now claiming (again contradicting things he's said previously) that he had intended all along to film Episode VII and have it in theatres this upcoming May, 2015. Realizing how much of his life he'd have to set aside in order to complete this third trilogy, he apparently jumped at the chance to sell the entire kit and kaboodle once Walt Disney showed up with his checkbook.
So now after insisting for years that he'd never intended a third trilogy while having previously said his story was (originally) plotted out as three trilogies he's going on record apparently "to clarify" that there were three trilogies all along.
I guess it's best just to consider this report in The Verge as "George Lucas: The Special Edition." In other words, blame Greedo.
