Seriously this is so totally made up BS. There is no 'official' G-Cannon except for what some fan made up for their own personal rationalization and making things fit issues. I don't know how many times this has to be said or why so many proclaimed fans have missed this. George Lucas has already done an interview on this subjeuct and we have pretty good idea what the next films will be. While Lucas isn't helming it, it is still going to be based largely on his ideas for episodes VII-IX. It's not gonna be a reboot and it's not going to contradict the first 6 episodes. There is no D-canon.
You should probably do your homework. Leland Chee and George Lucas created a canon system to keep the EU in line with the movies. G-Canon is an official part of the canon system, and I'm hoping Disney adds their own part so that everything can remain organized.
