Are you not clear exactly as to what parts of "Star Wars" are considered canon and what's not in relation to the upcoming "Star Wars: Episode VII" and the upcoming spin-off films?
The franchise's new captain, Kathleen Kennedy, recently spoke about just that issue says Yahoo. In the process she reveals that the spin-off movies, set to be released between each episode of the new trilogy, will NOT involve any of the characters from said new trilogy.
"George was so clear as to how that works. The canon that he created was the Star Wars saga. Right now, Episode VII falls within that canon.
The spin-off movies, or we may come up with some other way to call those films, they exist within that vast universe that he created. There is no attempt being made to carry characters (from the standalone films) in and out of the saga episodes.
Consequently, from the creative standpoint, it's a roadmap that George made pretty clear."
This would put a damper on the talk of a Han Solo spin-off film considering Ford is a confirmed part of "Star Wars: Episode VII". It also lends credence to the talk that one of the films is a Boba Fett story.
"Captain America: The First Avenger" Joe Johnston has been suggested as the front runner to direct the Fett standalone film which, according to Latino Review, could see a drastic change to the character.
According to them, Lawrence Kasdan is working on the Fett solo feature and reportedly isn't a fan of the clones story arc from the prequel trilogy. As a result, there's talk that Jango Fett's son will be killed off quickly with a new character taking the armour and weapons (and name) - this will be the version of Fett we see in "The Empire Strikes Back".
