Better chip, cheaper prices. And frankly, what does the average person do that needs more than 16 GB of RAM? You say we will have to wait, as though you are going to do something that requires more than 16 GB. What would that be, really?

It looks like Intel, not Apple, is to blame, if you want to call it that, for some of the limitations. Mary Intel's chip design, not Apple's choices, reason behind Thunderbolt 3 & RAM issues in new MacBook Pro AppleInsider The processors in the new 2016 MacBook Pro line have been identified, clarifying why some of the limitations surrounding the machine —like limited Thunderbolt 3 bandwidth on some models —exist. [http://photos5.appleinsider.com/gallery/18844-18371-mbp-top-l.jpg] After the furor of the initial "Hello Again" event died down, speculation began about the new MacBook Pro line, and seeming design choices that Apple made, which some believe compromise the machine. While Apple did make some choices, many of them were dictated by the limitations that Intel has placed on the company while the Kaby Lake processor family develops. Skylake in the 13-inch 2016 MacBook Pro The base-model dual-Thunderbolt 3 2.0 i5 GHz processor has been identified as the 6360U processor. The 6360U launched<http://ark.intel.com/products/91156/Intel-Core-i5-6360U-Processor-4M-Cache-up-to-3_10-GHz> in the third quarter of 2015, using Intel's 14nm process as with the rest of the processors in the new MacBook pro, and has a maximum turbo frequency of 3.1 GHz. Thermal design power on the chip is 15W, and it, like all the dual-core processors across the MacBook Pro line has a maximum of 12 PCI-E channels. An upgrade option for the 13-inch dual-Thunderbolt machine is the dual 2.4 GHz i7 6567U<http://ark.intel.com/products/91167/Intel-Core-i7-6567U-Processor-4M-Cache-up-to-3_60-GHz> processor. It has a peak of 3.6 GHz, and has a thermal design power of 28W. 13-inch quad-Thunderbolt models The 13-inch quad-Thunderbolt 3 has three processor choices —the base model has a 2.9 GHz dual i5 6267U processor, with upgrade options for a 3.1 GHz dual i5 6287U, or the same 3.3 GHz dual i7 6567U as found in the dual-Thunderbolt version. The i5 6267U has a max speed of 3.3 GHz<http://ark.intel.com/products/91166/Intel-Core-i5-6267U-Processor-4M-Cache-up-to-3_30-GHz>, and has a thermal design power of 28W. An upgrade to the 6287U dual i5<http://ark.intel.com/products/91164/Intel-Core-i5-6287U-Processor-4M-Cache-up-to-3_50-GHz> will give the user a peak speed of 3.5 GHz, with the same 28-watt thermal design power as the other upgrade processors. 15-inch quad-Thunderbolt The 15-inch quad-Thunderbolt MacBook Pro also has a choice of three processors —the 6700HQ<http://ark.intel.com/products/88967/Intel-Core-i7-6700HQ-Processor-6M-Cache-up-to-3_50-GHz> 2.6 GHz, 2.7 GHz 6820HQ<http://ark.intel.com/products/88970/Intel-Core-i7-6820HQ-Processor-8M-Cache-up-to-3_60-GHz>, and 2.9 GHz 6920HQ<http://ark.intel.com/products/88972/Intel-Core-i7-6920HQ-Processor-8M-Cache-up-to-3_80-GHz>. Peak turbo speeds are 3.5 GHz, 3.6 GHz, and 3.8 GHz, respectively. All three of the quad-core processors have a 45-watt thermal design power, and 16 PCI-e lanes. Implications of Skylake in the MacBook Pro All three of the quad-core processors available in the new 15-inch MacBook Pro have 16 PCI-e lanes, which is what allows for for max Thunderbolt bandwidth on the 15-inch model. Related, the 12 lanes on the 13-inch models are responsible for the "reduced bandwidth<http://appleinsider.com/articles/16/10/29/two-of-four-thunderbolt-3-ports-in-new-13-macbook-pro-with-touch-bar-have-reduced-speeds>" on the right-hand side ports on the 13-inch MacBook Pro. Additionally, the quad-core Kaby Lake processor still having not seen the light of day has caused other problems that are being attributed to Apple, and not as having been foisted upon the company by Intel. For low power consumption, Skylake only supports LPDDR3, which is limited to 16 gigabytes. LPDDR4 will not be supported in MacBook Pro-bound Kaby Lake quad-core processors until possibly the end of 2017, and perhaps later. macOS isn't the limiting factor, and hasn't been for some time. While Apple chose to not implement other technologies to boost the RAM capabilities of the MacBook Pro, it chose to not do so, in the interest of a thinner machine than previous generations, and longer battery life than it would have had had it implemented non-LP RAM workarounds. Apple's statement that other RAM choices allowing for 32 gigabytes of RAM or more would cause decreased battery life is accurate, if not quite specific.
