If there's no Mac Pro Mid/Late 2016 announcement at WWDC2016 I think that's a pretty big kick in the teeth.
I realise laptops and iOS devices are probably their main sources of income, so obviously their focus should be there. But Apple was the forefront content-creation tool professionals had to have, and that line is begging to wain a little. I'm sure their modern laptops are great, but they won't ever be as powerful as a desktop system; they might be trucks, but trucks still have their functions.
There have been so many advances since (and even before) the 2013 Mac Pro was announced;
- SM951
- NVMe, 950 Pro
- Fiji
- Pascal (MXM anyone?)
- Haswell-E
- Broadwell-E
- DDR4
- Thunderbolt 3
- USB C (3.1 rev2)
Looking at their previous released, they were always a good year or two behind with GPUs, so to repeat an earlier post of mine, it's my belief that they'll launch a new Mac Pro at WWDC2016 with 2x downclocked Fiji chips on a bespoke PCB. Could well be Broadwell-E but might be Haswell-E, depends how long their testing requirements are (could always be announced now and released 'Late'.
A Samsung OEM NVMe 951/961 should be a given at this stage, as should DDR4 if the corresponding CPU supports it.
But then this is Apple, who knows! Apart from possibly
