How many of us have bought or built sabers of EU characters or based on EU material? I have one in my build cue right now and in a couple years might be told it is just a random lightsaber with no 'canon' history.
IMHO, people take 'canon' too seriously. If something happens that I don't like, I simply ignore it.
Its kind of like all the different movies and books about batman. He dies is several of them. Yet books still come out with batman still alive. In some of them, he is young, in others middle-age, in others an old man. I don't see a problem with picking and choosing the story line that you want to follow. Isn't that what makes it fun???? :D
Batman and most comic books are very different from Star Wars in a very important way.
There are many different versions and types of batmen from over the years. In Star Wars there are teams and data banks and sections if LfL that make sure there is only one Luke skywalker.
Star Wars consistency is one reason I can invest in it so freely(very expensively actually lol) and it makes it more real for me.
I know I'm a big baby bought this. :-[
