Recent developments in holographic storage might mean that formats based on this idea are closer than we think. GE Global Research in early 2009 announced that it had developed a holographic storage material capable of storing 500GB of data on a DVD-sized optical disc – ten times the amount that can be stored on a dual-layer Blu-ray disc.
(expect commercial devices 2012). IMHO, the real question is, will Blu Ray take off by then or is it just a niche market, that will be largely ignored by the masses esentially waiting for something better. Things tend to be very expensive the first year or two, so blu ray may have another year or two to reach >50%. Personally, I doubt it will, but it might by 2014. If it doesn't by 2014, it will be too outdated, and the industry will have to pick a new format.
