I don't think this has anything to do with Macs and everything to do with iPhones and iPods. Moving those systems to newer ARM processors designed by PA could be one goal. Or Apple could change the iPhone processor to Power, and since nothing is specifically developed for ARM yet, then a transition from ARM to Power on the iPhone would likely be relatively easy.
I doubt apple would ever go back to Power for the simple reason that Intel is able to decrease apple's costs and guarantee high volume production and ramp speeds. Also it would destroy the current mindshare and marketshare expansions Apple has made by getting rid of windows compatibility.
