There's simply no point for Apple to switch desktop CPU architectures unless there's a unavoidably compelling reason to do so. The move to Intel met this high threshold easily. A modest cost saving doesn't qualify and would be partially swallowed up by R&D costs. Energy/thermal savings might be a reason in theory, but how much of a laptop's energy use goes to the CPU anyway? Apple seems to be doing just fine with Intel's low-TDP parts anyway.
