That article might be better titled "Half-height Optical Disc Drives To Be Obsolete In Consumer Desktop Computers by 2014.
Optical media manufacturers like Panasonic, Mitsubishi Kagaku, FTI, and Taiyo Yuden have invested significant resources recently to cater to the data archive market with archival caliber discs. And the use of CD/DVD/BD for back-up, distribution, videographer, and business/government archives is not yet a thing of the past.
Pioneer just released a half-height archival BD burner.
The market for replacement half-height drives will keep them in production for a bit yet, I'm sure. Though if they are actually phased out in new desktops, we will likely see fewer new models introduced in the next few years. Possibly only from the likes of Pioneer and LG. And of course Asus will likely continue to sell rebadged drives in the enthusiast/upgrade market.
