Scobleizer: Sony didn’t learn from Beta format mistakes

Beta and VHS were physically different media formats that could not be played by the same player.  Dual-format media and dual-format players (which I’ve advocated for two years) along with the PlayStation 3 will keep both Blu-Ray and HD-DVD in the marketplace.  Would adoption occur quicker if there were one format?  Sure.  But it’s not necessary.
