An 800GB DVD has been patented recently, which blows the doors off of any Blu-Ray media out there. DVD is still considerably faster then Blu-Ray as far as search times and load times are concerned. HDDVD is still DVD, and is fully backwards compatible with normal DVD's in every case I have heard. As far as I am concerned DVD will remain to be the format for a very, very long time.

Iomega Corporation announced that the United States Patent & Trademark Office (USPTO) recently issued a highly notable patent to Iomega for its work with nano-technology and optical data storage. On April 12, 2005, U.S. Patent No. 6,879,556 titled Method and Apparatus for Optical Data Storage was issued to Iomega. This patent is the first in a series of nano-technology-based subwavelength optical data storage patents sought by Iomega.
The patent covers a novel technique of encoding data on the surface of a DVD by using reflective nano-structures to encode data in a highly multi-level format. This technology, termed AO-DVD (Articulated Optical - Digital Versatile Disc), allows more data to be stored on a DVD and could allow future optical discs to potentially hold 40-100 times more information with data transfer rates 5-30 times faster than today's DVDs, and at similarly low costs.
This invention was recently recognized as a winner of the Nanotech Briefs' Nano 50 awards in its product category. The Nano 50 awards are given to the "best of the best" in the industry - the innovative people and designs that will move nano-technology to key mainstream markets.
Iomega is working to investigate the commercial feasibility of this format and other nano-structural data encoding formats. One possibility being investigated, termed NG-DVD (Nano-Grating - DVD), uses nano-gratings to encode multi-level information via reflectivity, polarization, phase, and reflective orientation multiplexing. Iomega is concurrently evaluating and developing appropriate partners to leverage this intellectual property for producing commercial data storage devices.
"Subwavelength optical data storage can provide an array of mechanisms by which the state of a focused spot of light upon reflection can be precisely changed. This is the key to new commercially interesting multi-level optical data storage that this technology represents," commented Fred Thomas, Chief Technologist, Research and Development, Iomega Corporation.
"The nano-replication technologies that are used to fabricate these structures at low-cost are just emerging from various labs. I believe the scope of Iomega patents issued and pending in this area, in conjunction with these exciting new nano-replication technologies, will make this a fertile area for optical data storage development and innovation for years to come. As high definition content becomes more pervasive, Iomega sees significant technology partnership and licensing opportunities for this intellectual property."
Thomas will present an overview of subwavelength optical data storage technology at the prestigious Information Storage Industry Consortium (INSIC) symposium in July in Monterey, CA.
