Wouldn't matter. It would all be incremental volume for Intel on the iOS side.
History repeating itself. Apple will likely be pushed to a smaller market share due to its high-cost, vertically integrated approach and become a niche player like it is in PCs. But they will be around.
Again, for Intel, it would be incremental volume...so 10 million SoCs, or 20, or 40, or 60...we will take it.
As far as logic semis are concerned, Intel will be an arms merchant once its CPUs/SoCs deliver more on the power/performance front.
