The new high capacity DVD formats blu-ray and HD-DVD are going to show presence at the CES 2005 this week.

The Blu-ray Disc Association has several speakers placed in events. The press announcements says: "The speaking engagements communicate to the consumer electronics industry how Blu-ray Disc will maximize the high definition experience for content providers and consumers alike."
The HD-DVD Promotion Group formed by Toshiba, Sanyo and NEC is of course also present at the show. NEC will show its recently announced HD DVD Drive that supports HD-DVD, DVD and CD. I will keep an eye on new Blu-ray and HD-DVD devices at the CES.
