If Intel will cut AMD the entrance to x86, they might get it from Via.
And if they don't they will need to come up with another architecture, which might be similar to better.
Then AMD will become totally independent on intel,and Intel might shoot itself in the leg; especially if there will be companies providing support for this newer technology.
Besides, AMD theoretically is still allowed to run x86 in simulation,without paying Intel a single penny.
If AMD starts working together with via or samsung on a CPU architecture, they could deny Intel connection to the architecture as well!
So as long as AMD will be strong enough to survive, it can do more damage then you'd expect to Intel.
Plus, it might get rid of Microsoft as well, by using a Linux based operating system, something MS would probably never do.
But a market like this is no longer a healthy competitive market, but more like a market to promote monopoly, something absolutely forbidden in Europe. So the European market will take notice, and probably bring it to court.
