Besides, since when have LA been able to know ANYTHING about cannon consistency? Compare the character and ship designs in, say, Knights of the Old Republic and the Sith War trilogy found within, to the stuff that was found in the two games and what has been seen in TOR (and it's been specifically said that the art style was forced on Bioware by LA).
Mandalorians went from actual aliens to dudes in armor.
Basalisk war droids went from having the Mandalorian ride it and looking insect like, to being a starfighter from the book/game Shadows of the Empire
The Sith War where Courescant was invaded became a minor scuffle in popular culture.
As to Kreia, the only person who could give us a firm idea on her motivations (despite your protestations gromm) would be Avallone. It's his character, he knows what she really would be thinking and what she really wanted to do.
