I'm not sure you'll see a true second generation chip, I would be expecting it to be mostly the same thing, but with more cores and some solution to providing more RAM. Having said that, Apple does have something of a history of pushing out v1 of a product that sets a high bar for everyone else to try and catch up with, then immediately pushing out a v2 that raises the bar well above where everyone else was aiming. Overall though, it's awesome that the Macs now get to benefit from the vast investment going each year into making faster/better CPUs every year, for hundreds of millions of new iPhones.
