Definitely surprising that no spec bumps at all happened for any Mac. I've not followed Intel's roadmap closely lately, though I was at least expecting some Skylake bumps. The Q1 2016 and TBD lining this chart might be a factor. I'm also thinking Apple wants to jump to Thunderbolt 3 soon too, including a possible retina/5k replacement for the Thunderbolt 1 monitor/docking station.

Some interesting accessories USB and Lightning wise. A new Lightning to USB3 Camera adapter that has both a USB B and USB C lightning port. The use of USB on the iPad side grows a bit, with it officially supporting USB C ethernet adaptors, beyond the already in use USB Microphone or MIDI device. Someone is theorizing the iPad may also accept power charging through that adapter on the USB C port. There's also USB C to Lightning cables that were missing during last years Macbook with USB C launch.

The Apple Watch entry level did drop in price $50, down to prices some stores were already selling it at. The iPad Air 2 remains in the lineup, also down $100.
