I thought the Clone Wars cartoon was writing over a lot of EU canon anyway. And it's not like this is the first time this has happened. The prequels undid a lot of EU material that existed up to that point.
If you read through the extensive discussion of canon on Wookiepedia [http://starwars.wikia.com/wiki/Canon], it's clear that through the whole history of the franchise, whatever happened in the live-action films is canon, and any other media is generally accepted as canon until Lucasfilm decides it isn't.
Lucasfilm has the right to mine whatever ideas they like from EU canon, and they probably will use a couple. But adopt that byzantine web wholesale? Not likely.
