Not necessarily. Chip designing and fabbing is a complicated and resource intensive business (especially at this stage of Moore's law) that would be an unnecessarily heavy drain even on a company like Apple.This is what happens when you're at the mercy of Intel.
Imagine if they created their own chips for Macs? Then you'd get your updates (at least once a year).
The foundry part of it at least, is best left to the Intels, Samsungs and TSMCs of the world.
