According to Samsung Blu-ray has only 5 years of life

In an interview, Andy Griffiths, director of the UK consumer electronics division for Samsung acknowledged he thought that the format Blu-ray did not have more than 5 years of life.
Similar declarations by Toshiba were related to its loss of the battle of the blue laser, however Samsung is a full member of the clan supporting Blu-ray and this gives much more weight to this opinion.
