BTW TDK and Maxell have both developed 200GB multi-layer Blu-Ray discs to be commercialized around 2009. IMO strange to compare Blu-Ray with Betamax, one of Betamax' weakpoints was storage capacity, this is not the case with regard to Blu-Ray. Also Blu-ray isn't Sony's format, it's the format of choice for most related leading consumer electronics companies.

Most HD DVD movies require two layers as one layer won't fit the content. For Most Blu-Ray movies it's sufficient to be stored on just one layer. Note that dual layer production costs are higher, so in most cases Blu-Ray is cheaper.
