I
can state new Mac Pro's, iMac's,
and display's have been waiting in the shadows. I posted this explanation yesterday but will trim it down as it's a read.
Intel's missed releases benched new Mac prototypes. Numerous delays prompted the decision to release new MacBook's before the holiday season. Updated desktop systems will be released next year as some models require Intel's improvements in integrated graphics while other models will offer professional level BTO options with dedicated GPU's and server class CPU's. Refreshed displays with possible dedicated GPU's have also been developed. Waiting for CPU and GPU advancements has been a hurdle for production cycles, most notably the "X" nomenclature replacing "E" and "K" CPU's.
Skylake-X and Kaby-X
In June, Intel announced ditching the E and K nomenclature in succeeding the Broadwell-E chips with the introduction of "X" for its Skylake and Kaby Lake processors. Unfortunately, constant delays meant benched Mac's. Primary interests were Thunderbolt 3, improved integrated graphics and 4K+ support, Xeon E3-1500 v5 server chips, etc. We held back as Kaby Lake was on track for a Q2 2016 launch with "X" variants in June promised no later than Q3.
In August, Intel announced Skylake-X and Kaby Lake-X would be shelved until late 2017. Some close to the situation claimed Cook channeled Jobs' level of anger as Apple began seeing declines waiting for Intel to get it together. Rumor mills suggest a possible move towards in-house production for crucial components (CPU's) while introducing high-end dedicated GPU display components with new production lines.
