The director of the movie is a hardcore fanboy of the series. He visited the Lars Homestead in the Tunisia desert and took milk with blue dye to drink there So that might mean he will make an amazing movie or it could mean he might try to hard and fuck it all up.
As a fan boy I'm stoked that Disney is releasing a movie every year. I read a good point either here or an article somewhere, that said Lucas had the right idea. Making the movies scarce made sure to have the fans in a frenzy. Now it's kind of overkill and people will probably get bored with the movies. For me though I'd rather have a good movie every year than wait 16 years for a huge pile of poo.
