DigiTimes has reported that Lite-On will begin volume production of 18x DVD burners in July. Most surprising is the company's plan to begin production of 20x DVD burners in the fourth quarter of this year.
Lite-On IT will begin volume production of 18x DVD burners in July and plans to start production of 20x DVD burners in the fourth quarter of this year, according to Michael Gong, the company's Optical Disc Drive Business general manager, at a press conference following the company's 2006 shareholders meeting on June 15.

As OEM prices of 16x DVD burners drop further due to intense competition, the switch to production of more profitable 18x and 20x DVD burners is aimed at keeping overall gross margins from falling, Gong indicated.
The article also mentions that Lite-On will start volume production of Blu-ray Disc and HD-DVD optical drives in August. If you'd like to read more, head on over to DigiTimes.
