On second glance, it's a staggering deal. Remember, this isn't 'simply' Star Wars; it's all of Lucasfilm, including the Indiana Jones franchise, and films like Willow and of course Howard the Duck, as well as companies like Lucas Licensing, Lucas Books, ILM and Skywalker Sound and all of the rights associated with them.
I also liked this tidbit.
Also, just as an aside, it's fun to note how interconnected all of this is. Not only has Disney and Star Wars had a lot of crossover merchandising for years, but Pixar sprung from Lucas's first attempts at digital filmmaking, Marvel jumped into bed with Star Wars for the comic books as early as the late 70s and The Muppets have had several similar Star Wars crossovers (and of course a certain 3' green jedi master).
And that just scratches the surface.
