The DVD forum has recently announced it's backing the HD-DVD format rather than bluray, so it looks as if sony has created the beta/superbeta/betacam/minidisc/umd/SACD/PDD all over again, not to mention TDK already has talks of introducing a 6-layer 200gig media, and of course the D-data DMD (formerly called the FMD) which uses the more stable red-laser format, but can hold 1TB per disc, and the Optiware HVD which is actually a holographic media which can store 3.9TB per disc, and already has drives available for professional and medical data storage.
Blu-ray will be another dead sony-only media format.
I don't understand why they always have to have their own incompatible, proprietary format.....
