Surprised not to see a thread on the very cool video Hangout Anand did with Peter Greenhalgh, ARM's lead architect on A53 among other designs.
Anand asked him flat out what he thought the next-gen "superphone" SOC arrangement should be. Interestingly, he suggested 4 little (A53)+2 big (A57), contemplating not just little<>big task migration but the new setup that supports every CPU core running at once. Apparently even with games you won't see more than about six threads, with most of these being minor.
(Given how powerful Apple's SOC is with just the two big ARMv8 cores, this makes sense.)
Even more interestingly, when pressed for a tablet SOC, Greenhalgh suggested the same CPU setup with the extra thermal/power budget going to a bigger GPU for gaming performance. Fascinating.
I hope someone out there is listening/has listened. Exynos 6 for hexacore anyone?
