Via Opposable Thumbs, an article at GamePro in which Phil Harrison clarifies that Blue-ray on the PS3 is a 'game design' decision. From the article: "Once we had that storage capacity on Blu-ray Disc, adding the movie playback functionality was extremely cost-effective, [the cost] is actually non-existent. So games like Resistance which, as a launch title, is up to 20-something gigabytes already. And that's day one -- think about four years, six years from now. We'll be pushing the 50 gigabyte limit with dual-layer Blu-ray very quickly. So we absolutely need it as game designers, and in that regard, the consumer is getting the movie functionality effectively for free." I probably would have had a follow-up question there, but that's where the interview ends. So what do you think? Which came first for Sony: Blue-ray as new movie media, or Blu-ray as answer to design challenges?
