I don't understand why Star Wars fans are bitching about this. This is great news. All that Lucas managed to do since the 80's was to mess up the series and re-re-re-release the good part. The only really good thing was the game studio which will now get a big boost in funding and more franchises to play around with.
And Disney has some really good parts. The 3d animation division (not Pixar) has done some amazing movies, while their films have grown quite ballsy (consider how Prince of Persia somehow managed not to suck). And let's face it guys... ewoks? I've seen Disney movies that were less "Disney" than the 6th movie, and 100 times less than the 3 new ones.
I have a ton of faith in Disney to deliver something good. A 7'th movie is so easy to make, I'm quite amazed Lucas didn't do it himself. Hire the old boys, stick with the 80's feel, come up with some Darth Lord that tries to rekindle the Empire. Heck, why not Luke himself? Rebellion wins, grows corrupt, small wars break out, Luke being the only Jedi left standing tries to renew the Jedi Council, install order in the Galaxy. All hell breaks loose, he's accused of going to the Dark Side, an Alliance is made against him, Han is sent to reason with him (in fact a Trojan Horse), Han learns the truth at the end, joins Luke for the second movie. And guess what... we can finally fantasize about Tie Figthers being the good guys. They look Solar Powered so they can't be bad...
And yes, I do realize that there absolutely zero chance that the 7'th movie will actually have this story

More like "guy from Twilight" learns to be a Jedi from the ghost of 3d animated Yoda then fights an ewok, in a pod racer. End credits.
