IMO Microsoft misleads consumers, Microsoft before the PS3 launch claimed HD DVDs are future proof and claimed it can store more data as one of its key benefit:
Microsoft:
"This is an opportunity for consumers to buy discs at launch that future proof their collections — in other words, helping assure customers that the discs they buy will remain viewable in the future."
"Superior capacity. HD DVD-ROM discs will offer dual-layer 30GB discs at launch, compared with BD-ROM discs, which will be limited to 25GB."
Of course we know Blu-Ray provides more storage per layer, so why wouldn't this be a key benefit for Blu-Ray instead? Now that HD DVD is on the losing end of the "war" they change their tune towards the internet.
