I think you hit the nail on the head. Isn't the plan to release a movie every year? Episode - Spinoff - Episode - Spinoff - Etc... And that's not even mentioning the new books and other merchandise they're going to be releasing on a regular basis as well. It'll be significantly less than 37 years before the canon universe exceeds the Legends universe in size. With $4.5 billion+ dollars to make back, I don't blame Disney for clearing the decks. Every EU novel/game/comic/etc. they canonize is one less slice of space and time they could fill with their own product. The new is naturally going to be more lucrative than the old, especially with tie-in movies coming out every year to stoke up and expand the fan base. That's not to say that I resent what they're doing. Even though it's purely a business strategy, the result is that they're going to be pumping more canonical entertainment into the Star Wars fandom at a faster rate than ever before. That's good enough for me.
