While we can't say if it represents a general sentiment at Samsung or not, the company's UK director of consumer electronics, Andy Griffiths, sure went out on a bit of a limb in a recent interview with Pocket-lint, with him saying that Blu-ray has, to paraphrase David Bowie, only "five years left," and that he "certainly wouldn't give it ten." He did say, however, that he thought 2008 would be Blu-ray's year, adding that "it's going to be huge", and that Samsung is "heavily back-ordered at the moment." As for Samsung's future after Blu-ray's supposed demise, Griffiths seems to think that OLED will be the next big thing, and he's pegging 2010 as a possible date for it to become mainstream and replace LCD. He didn't offer a prediction as to when it will die out though.
