HD DVD vs Blu-Ray
Looks like the Blu-Ray camp is making an attempt to end the format war. Warner Bros just signed on as an exclusive, meaning now about 75% of studios are Blu-Ray exclusive.
I still think this is a bad idea, because the lack of a combo format means stores will have to stock two SKUs for every movie for the next ~10 years, but if it means we can just pick a format and move on, then maybe we're better off.
Warner's reason is a good one - that they believe consumers are going to sit on the fence until this gets sorted out, so the industry needs to choose a clear winner to remove this uncertainty - but Ithey've picked the wrong winner.
