I tend to appreciate it when an author (or filmmaker, or what have you) makes an effort to keep continuity with what came before. I'm the kind of nerd who loved the mini-episode of Doctor Who "Night of the Doctor" because of what I perceived as charitable acknowledgement of the audio dramas that the neglected 8th Doctor has been featured in.

My tendency would be to look at Star Wars VII and hope that they do their best to situate the story within the established storylines that have filled in the gap for the past 20+ years. Ideally they'd not depend on details from the EU, but just establish their new films in the same continuity.

In the end, I want them to make the best film they can, though it'll be a little uncomfortable to let go of the continuing narrative that has been contributed to for so long. I think that's because we've come to love the characters and have enjoyed watching their lives unfold. I wouldn't be angry about rebooting the EU, but maybe somewhat melancholy about the past couple of decades' worth of stories that have formed a cohesive continuity.

I get the impression from the rumors, taken with salt, that the 'story group' likes the EU quite a bit as well and has an interest in preserving it. As a fanboy nerd anal-retentive kind of guy, I would be very appreciative of a frank, clear-cut announcement of, for example: "Everything set after Vector Prime is no longer in continuity. That is all." I'd prefer that over having to parse everything once details about the movies come to light and having to fuse them together with a wholly unrelated EU continuity.

In the end, any upsetting of continuity is well worth getting more films. I'd throw out all the books and EU stuff if it meant getting one more movie with these characters. But surely one can understand how a fanboy would feel sad about being told, for example, "The Solo children you know never existed."
