You know, I have a solution to the format wars. It's such a simple idea, that I really can't believe that no one ever came up with it.
Put all media on one standardized form of flash media. That way, the only thing we'll ever need to buy is a backwards-compatible player to play all of our old flash movies.
Basically, you're buying a mini flash drive that contains your movie, game, software, ect. I don't see how this couldn't be a good idea, it's not like the don't pirate movies now. Of course there will be tons of pirating, but you can find EVERY movie, game, and piece of software that you want on the internet anyway. Why not just settle down on one final format that can change as computers change.
I already predict that computers will integrate into our entertainment centers, and I can even fully do it. No more conventional televisions, no more receiver/amps (maybe a pre-amp for the audiophiles), and your DVD player(s) are built into the computer.
