I second that!
it was really disappointing to learn the Galaxy S4 will not come with this bad boy!

The cores not in use don't completely turn off, they just run idle, not really doing any work so they use almost no power; but they're ready to ramp up when needed.

Otherwise, yes, turning them completely on or off would be very inefficient.

The one part of big.LITLLE i.e either four A15 cores or four A7 cores are turned off at one moment, and they are switched if needed.
All eight cores can be turned on through drivers but that would be pointless.

Computing has long been working like this, if you monitored your computer CPU you'd also see it switching between clocks, modes, cores. It's all one CPU divided to 4 A7 and 4 A15 cores, so it's always on, but only draining power of the actual cores in use, hence the power efficiency.

You mean for future Octa-core devices? No rumors on that one so far other than the SIV not being one. They are only demonstrating a pre-recorded video here so the Exynos5O it's still probably in pre-alpha stage.

Anandtech said the Exynos 5 Octa would use PowerVR graphics, SGX544MP3 specifically, but it was never confirmed.

Ah, thanks, I never saw the confirmation post. Kind of a bummer, I wanted to see what the Mali-T678 could do and how it stacks up against the SGX554MP4. The SGX544MP3 is very capable I'm sure, but I wanted to see a second gen Mali-600 in action.

It's just reference hardware to demo it in.
