It's already taken the plunge at a number of retailers, but Microsoft has just now gotten official with the new $129.99 price point for the Xbox 360 HD DVD add-on (which still includes a copy of King Kong and the offer for five free HD DVDs by mail). Of course, that price is the MSRP, which means we could very well be seeing even bigger discounts on the drive at retailers, even if they aren't all as steep as Amazon's all too brief $80 bonanza.
