That is what some people thought when Apple added that requirement. In reality, the differences in processors that this process currently can deal with is that between different versions of ARM processors. The system might evolve into something that is able to bridge the gap between ARM and Intel, but that is still a long way off.Things will not be the same since it is not the same process when it comes to ARM/Intel. In the Rosetta age applications were written and compiled down to byte code (down to the machine language) by the application developer. Rosetta was more of a processor emulator which means that the code itself did not run on the processor, but ran on another program that saw PowerPC code and then emulated the PowerPC and translated it to the Intel platform. Since around 2008, Apple has switched from compile technology that compiles down to bytecode to a bitcode (a cross processor architecture assembly language/binary) that the LLVM compiles into specific processor technology. Usually right now those two steps are done on the developers computer and then uploaded to the app store. The change has all applications being uploaded to the app store as the LLVM bitcode and then as advancements occur in optimization the app store "compiles" it down to the binary (though technically this could be done both as part of installation on OS X as well - technically the same) for a specific processor. As time goes on all the applications as they are updated all will be in that format, then at a certain point Apple will drop any applications that have not been updated (similar to what they did with 32 vs 64 bit). That means that all applications in the app store are basically natively compiled down to whatever processor the customer's computer is running - it is not emulating a processor to run the application... it is not translating different operating systems... it is native operating system (OS 9 and OS X were different operating systems). It will no longer require rosetta or similar transitional technology for changes from processor families like before.
Yes, 15 W would need a fan but the TDP between the 13" and 15" MBP is quite different as well, in particular once you add the discrete GPU. And re-classification of existing laptop designs has happened before, note the 13" MB that turned into the 13" MBP.One is fanless technology, one requires cooling to be built into the case.... two completely different case designs. Fan requires a bigger case, so you might call it the same but it would look different the size would be different which means you would just be renaming the air and not changing the design.
There could be a 5-ish Watt 14" Mac laptop alongside a 15-Watt 13/14" model and alongside a 27-Watt 13" one. But usually Apple tries to keep its model lineup very slim (so it has been messier with drawn-out successions, see the 13" non-retina MBP). Segmenting power envelope by screen size a standard way to do so. Note the absence of a 15" MBA (there certainly is demand for a MBA-like processing power combined with a 15" screen, but Apple decided not to cater to that).
I am fully aware of that, that is why it is called Thermal Design Power (TDP).The wattage on the CPUs has to be with heat generated - not the power to run them (though their is a correlation obviously)
