Probably because this thread is months out, the DVD has been out for sometime now, and the original topic is no longer relevent.
Why are some people such stricklers that they can't cope with a topic wandering off slightly for a couple of posts?
Anyway, they were talking about other movies by Lucas and their DVD/Blu-ray releases, not their favorite snake foods, so it really isn't that off topic. However, counting in your post and mine, it is pretty far off topic now.
