disagree... flash memory is building soo fast, i think there will be a high definition solid state format within 5 years, optical drives will be obsolete... they have 4 gig micro sd now, how long until a 50 gig flash drive comes along? then how long until it's WAY cheaper to produce than an optical disk? blu-ray will die a quick death, because the novelty will wear off quicker than the price point comes down... even if you can get a decent priced blu-ray player, who wants to pay $35 for "step brothers" in 1080P? dvd will be around a long time, and may even outlast blu-ray because the cost/payoff isn't enough to warrant it for most movies...
