Oh, I could write for pages on this! Personally I'm very excited about it. Just got back from my local comic shop, and spent a good hour involved in a fun fanboy debate on this topic
Many are thinking it means the Disneyfication of Star Wars, but I think the franchise is in good hands and will be kept it's own thing just like Marvel. Overall I'm most excited about the future of the movie universe. If done correct, Lucas needs to step away and there should be a complete new blood injected to steer the universe for years to come.
Not sure if production is set to begin in 2015, or is a new movie set to release in 2015? Us comic geeks were mostly talking about a dream production team. I'd love Lucasfilm to take a chance like Marvel did with Whedon. For Producer or Exec-Producer of the New Trilogy I'd love to see someone like Whedon or Darabont ... people who understand story, but also CHARACTER over story. There's a ton of great writers from the TV and comic book industry that could inject new life into Star Wars. My dream writer would probably be Brian Wood (who's starting a comic set between Ep 4 and 5 in 2013) or Brian K Vaughan ... amazing comic writers who know how to handle characters and epic arcing stories. Director wise ... give a chance to Brad Bird or Rupert Wyatt. Would love to see Darabont or Whedon direct but I'd don't think they'd take on the task.
It'll be fun to see the response when the actual creative team behind the films are announced
