Their processors are basically RISC inside with an x86 wrapper already. So, intel will lose out because they need that RISC-CISC 'wrapper' but (personal opinion) I don't see why that wouldn't become fairly negligible. The big differences between ARM and intel are licensing and manufacturing, unless Intel have started to licence out designs for cores recently.
I don't think that the wrapper can ever be negligible. It has to do quite a bit of work. Now that work can be heavily optimised, but it is still work that takes power.
