The holiday push for Blu-ray is officially on. We've got name-brand players dipping below $200, and now we've got two mega-corps teaming up to promote the format this fall. Sony and Discovery Commerce, the consumer products arm of Discovery Communications, have inked a deal which will provide Sony Blu-ray deck buyers with a "gift-with-purchase coupon redeemable for an exclusive high-definition program sampler, Discovery on Blu-ray Disc, which features episodes from Fearless Planet and Sunrise Earth. The fortnight-long promo will launch on October 5th at over 11,000 retailers in the US, though there's no word on if a better, actually desirable promotion will follow after that.
