I'm not seeing the big news here, this has been known for months - the real shocker isn't the further delaying of Broadwell, but rather how Intel intends to minimize this release to quickly move to Skylake.
Broadwell will end up being a very minor "tock" to Haswell - Intel messed up, they screwed manufacturers over into waiting for it and then delaying, etc. Apple (and others) will end up having to use Haswell for way longer than intended, so they better find interesting features other than a processor bump to keep their sales from going south.
How would you like a Retina screen'ed iMac now, even if it runs on the same old Haswell chip?
