it's both probable and highly likely. if Apple didn't think it'd clear regulatory hurdles, they wouldn't be talking to ARM. and if you think this is just some crazy rumor, you're mistaken.
As I already laid out earlier, Apple will not cut licensing to anyone. As someone already astutely pointed out, ARM chips power waaay more than just cell phones. And the same chips in cellphones power other stuff like STB's. How retarded would it be for Apple to cut off licensing to Samsung when only a sliver of Samsung's revenue comes from cellphones? furthermore, Apple can't just tell Samsung "ok, you can sell your chips to Scientific Atlanta, but not Moto and HTC."
everyone needs to do exactly what you're chastising them for, smoke a joint, eat a cinnabon, and chill the f*ck out. this isn't a monopoly and it isn't the end of the world. Apple will license to everyone.
All this is about is Apple investing their cash hoard and saving some $$$ on licensing.
