Guys, try not to make multiple posts in a row. If you want to add something, edit your latest post. If that option is unavailable, I'll talk to Will.
On the discussion itself, ROJM brushing off canon because an author wasn't in the know about the new canon (can you link to interviews where this is stated, not that it has sway on Tarkin being canon, just curious) or because Disney now owns LF is getting ridiculous. It's just a childish approach to the whole discussion. Fact is, Kathleen Kennedy and the LF story group made the decision to clean up the canon and shift all but the movies, CG TV shows, and comics and novels starting with Son of Dathomir and A New Dawn respectively to the non-canon Legends designation. This fact cannot be disputed. We are not discussing Mega Drive sales numbers, we're discussing a fictional property where it has been stated time and time again what is canon and what is not.
At this point, we are arguing against ROJM's head canon, which he can happily enjoy on his own, but really should not be passing off onto us as fact. I personally like to think the Tales short story collections (Cantina, Bounty Hunters, Jabba's Palace), Darth Plagueis, the 2D animated Clone Wars cartoons, and the Ewok movies are canon but I know that is not the official stance. Still, I keep them in my personal canon until they are contradicted. That does not mean, however, that I'm going to try and tell you all that Charal from The Battle for Endor has a connection to the Witches of Dathomir or that Bib Fortuna ended up with his brain in a jar.
