Wont happen yet. This is just some analyst trying to get attention... big surprise there. At the moment ARM isn't capable of providing the horsepower for high to medium end computing. Perhaps in the next couple of years, however this "prediction" is just that-- a prediction. The switch from PowerPC to Intel wasn't so bad because many developers were used to Intel; switching from Intel to ARM is going to be a bit more troublesome because let's be honest, many iOS developers aren't exactly pumping out high complexity applications, and they're the only ones that would be ready for such a switch outright.
Maybe once regular PC's start to make the transition (along with Windows, which may happen soon) we could see this, but to put a date on it is a bit... preemptive. Especially to talk about something so jarring-- this isn't like OSX is just gaining ARM support-- now you're talking about taking something that's an offshoot of 10.4 and trying to tie it back into the main branch 10.7.... no small task.
Of course we're all worried about the loss of function and capability from such a merger.
