Yes they will...You just won't be buying from one entity anymore...
You'll be sending a cut to everyone with every purchase, even if you don't have multiple devices from multiple vendors.
Your cable company will show you that movie for free because you paid them $3 when you bought it for $65 at Best Buy (You also paid Sony, Disney, and whoever else wants in). Its not price fixing if everyone only sells the one product. Then it's just a monopoly with every company in for their chunk. If all the big kids play together then no one big enough to get lobbyists can go after them for cornering the industry.
Of course they still won't be able to plug what used to be called "the analog hole" since the community will build their own damn rippers/players from the chips up if they have to to avoid these schemes.
