Here's the deal. Spielberg (and George Lucas) don't hate DVD... they were just initially very skeptical about it catching on. You may see a lot of Spielberg titles now (although that is not a lot when compared to his entire catalog), but it was not always this way. When DVD officially "caught on" a couple of years ago, Spielberg (and Lucas) finally committed to it. But Nefrodite is correct, for the "important" films, Spielberg wants to be involved in the entire process of creating the DVD... he will have to record commentaries, assemble and/or approve deleted scenes, shoot new documentary footage, and basically make sure that every single thing that goes onto the DVD meets with his approval. It can be difficult to find the time to do all of that while you're busy shooting other pictures, attending award ceremonies, and dealing with all the B.S. that guy must have to deal with on a daily basis.
The other reason it hasn't come out yet? Deliberate, smart timing of Spielberg DVD releases by the production companies. They will space Spielberg DVDs apart a lot so they can make each one an "event". For instance they will do this with the upcoming E.T. DVD. They know they will sell more copies of it if they heavily promote it and get consumers frothing at the mouth in anticipation. Then they mass-produce the hell out of it and you will see it at Best Buy on sale for $17.99 or similar price point (a la Pearl Harbor--you know they must have made a bajillion copies of that thing).
Don't always believe the Digital Bits. It may be this year or it may not be, but it won't be too much longer.
