My desktop PC doesn't run on battery!
Also...I think that MS needs to make some changes to their O.S. in order to understand and use efficiently this mix of cores and also some firmware/bios changes - so it is not only up to them...
And to conclude:

That's ok for smartphones where you need to save battery, but i don't see the point in desktops, maybe in laptops.....

Next feature would return of big turbo button for turning on big cores..

Intel TURBO Edition (with a massive big red button on front of the case). I'm loving it already.

You hit the nail here...
Also this could happen if there is a bug and the "big cores" refuse to wake up with cpu intensive software:

I think that big button would be blue and they license Big Blue name for it:)

FINALLY
I've been asking for this feature in x86 for years! I don't know if it's going to work the way I expect it to, but I'm glad this is the first step forward toward CPUs with different types of cores.
Not all tasks are equal, so to create a one-size-fits-all CPU isn't very productive. I just hope the K/X models will allow you to independently overclock the small cores. That way, you get blazing fast single-threaded performance, and then use the big cores for highly complex tasks.

This is one of those rumors that either is completely false or has got it so wrong on what the CPU's purpose. Either way this big little concept only is needed in severely thermal constrained scenarios like in a phone or tablet so there is no chance Intel is doing something like that in a desktop CPU.

Removing SSE4 would be stupid. however AVX1/2 are not needed at all to achieve a good performance per watt in multimedia decoding.

You has not to be Nostradamus to see lows compatibility issues and incompatibilities with older SW, as when HT came or SMP with Ryzen, unless they will make it fully abstract on CPU level.. But i already see some threads named like.. pleas help my games is running on weak core.. how to switch it.. return of CPU affinity p*orn.

The Windows scheduler is garbage. Big/Little works on Android because they have their choice of many competent Linux CPU schedulers to pick and optimize from. Windows can barely tell the difference between a SMT/HT thread and a free core...and even when it can, many programs are hard-coded to run on a specific core (and Windows is not smart enough to force these to re-assign). Which is part of why Ryzen has performance issues on Windows with certain programs.
Windows also likes to re-assign threads to different cores repeatedly.. Because this makes sense on monolithic Intel to try to spread the load out between all the cores, but when some cores are superior to others, it causes other issues
