"....It's probably not actually going to happen....." Why not? After all, the content makers have been trying to find a new format to lock-up their product, reduce piracy and therebye ensure they can go back to charging rediculous amounts for their product. At the moment, DVD hire businesses like Blockbuster are dying if not dead, the cinemas are on their last legs, and the majority of people watch the majority of the films they see at home on a TV or PC via Internet delivery, DVD or set-top boxes. If the distributors can tie you to DRM-like mechanism that ensures you only get your feeds from a proper source (i.e., one that has paid the old media companies their dues) then they will throw money at both chip vendors and distribution channels to ensure it happens.
The switch to 3d films, which add nothing to the viewing experience for the majority of films, is a perfect example. The only real benefit is that the great unwashed, if they swallow the idea that 3d = better, have to go to the over-priced cinemas to see them, ensuring the old-media producers' (movie makers) and providers' (distribution companies and cinema chains) profits. The 3d bonanza seems to be running out of steam (it hasn't taken off on TVs), and seems just as vulnerable to digital piracy if 3d TVs do take off, so what are the old media companies to do? These people are smart, motivated and couldn't give two hoots about ethics, they will seek a lock-in mechanism by any legal means. And if Intel can get a market advantage over AMD/ATi and nVidia they'll probably take it too.
The only good news is that history has shown us that hardware encryptions have been broken before. ;)
