I can't link this but I know I read somwhere that Stover's deadline for the novel was before Lucas completely finished the script. Lucas prolly decised to show the wookie battle after stovers deadline. It could happen. Alos, i doubt any of the inconsistencies will be fixed in the movie. Lucas is the kind of guy that just wouldn't worry about them, then give some half-assed explanationon a commentary later that, although it seems to work, could have just been done right in the first place. He'll also go wohth the "They are just movies, settle the hell down and just enjoy them for that" In that respect I kind of agree with Lucas. Some people just try too hard to make sense of SW things. Others expect his storytelling to be author-like. Lucas isn't even close to the status of a high-prfile author. and because he won't let anyone else tell his story, editing out rather unimportant but still confusing inconsistancies and problems just doens't happen.
