So what about the these R7 Droids, are these ones cannon or just made up? I know that R7's exist, I just don't recall the pain schemes.
R7's are not canon...they are EU.
I thought EU was canon, and the non-canon stuff was Infinities and some issues of Tales...
Hate to dredge up the canon vs. non-canon issue, but...
LFL classifies the films ONLY as canon, and nothing's changed on that as far as I have read anywhere. The EU is considered part of, "The official continuity", but it's all basically sub-contracted story-telling to the overall saga, and so Lucas himself basically reserves the right to run right over any of it. A good case-in-point on this is Lucas basically was begged/pleaded with to call Coruscant, Coruscant... He had other ideas for the planet's name, but Timothy Zahn had established the capital planet's name in his trilogy, so Lucas was persuaded to go with it... Not everything was accepted though and some things have been trampled by the prequals or whatnot.
I've seen people try to apply some hiearchey to the EU (novels outweigh other materials, etc.), however nothing from LFL's ever said that. They seem to lump everything non-film into the EU category, and try to make it fit as best as possible... Things like infinities or whatnot seem to stand by themselves then, separate of the EU. Which is the fun of Star Wars... Lucas does allow creativity in it, and while it's all a cash-cow to him, it gives some entertaining stuff to us (and some crap too unfortunately).
I believe it was Lucas himself who said, "the films are gospel, the rest is gossip".
I don't know what that means for the live-action TV series, which he's supposed to be heavily involved in, and this new CW series he seems heavily involved in as well... Moreso than any other project(s) I can think of that he just usually signs off on.
