What I'm wondering is what kind of impact Maxell's new HVD (Holographic Versatile Disc) will have on the two formats. With storage capacities of about six times that of a Blu-Ray disc (initial releases are projected to have a 300 GB capacity), there's very little one couldn't do with a single disc. Of course, it'll be expensive when it first releases late next year; some are saying a single disc will be $100 US.
