The thing mention by AMS must indeed be seen in broader scheme. Intel are indeed trying to DESTROY ARM Ltd. This should be obvious and has been told by me for ages since Digital sold off their cpu-rights to Intel. That moment I knew we'd be in BIG s***. And trust me. We will.
ARM cannot add new (useless) stuff to their core. It's a matter of their licensee in the case they want to use the Core for to add new items to it. So ARM will not take drastic measure in this matter. But if some chip manufactor wants to use that core in a video-encoding chip it might ad it owns multimedia-instructions to it and sell it as it's own ARM-based cpu. In this case ARM can't take actions against Intel for this. But it'll certainly undermines ARM strategy.
Also. I am STILL Anti-INtel AND anti M$. Just because of their monopolistic nature. The same goes for Apple and Adobe. It appears common for big corporations to bulls*** everyone around!
