afaik, marvel and dc had restarted their series several times to accomodate different things, otherwise you would not have the same story told over and over again.

star wars decision was a simple one: they basiccally said that all work that has been done on the franchise, every book released and most of the games, are 0 and void as far as canon is concerned.

according to new disney canon: all movies+ the clone wars series are pretty much all lore that they have left officially.
