1. Movies are not getting longer. We have short attnention spans and if anything movies are getting shorter. 2. The studios have spent millions of dollars training us that multiple disc sets are better so just add more discs. It's possible that the cost to produce 2 HD discs is cheaper than the cost to produce 1 BD so just do 2 HD discs and maximize profit. 3. The authoring/codecs will get better so they will be able to squeeze more and more stuff onto a HD30 in the near term. 4. Long term, we need to integrate the purchase of discs with the internet. Ideally, in the future we will buy a disc that has just the movie on it. Then if we want added content we can go online to get it.
