Seems like quad-core A15 chips are a sure thing in 2012, very exciting.
By the time my contract runs out in 2013, there probably will be a few hex or octa-core chips. Though there won't be a lot of things that can utilize or need that many cores and the smart ones will be buying the higher clocked quads.
Man and I thought Dual Core chips were awesome! Now I feel that I'm going to be left out on the cool stuff that will be released next year. Still though my Rooted HTC Sensation clocked @ 1.51ghz dual core is still the best you can get right now.
Hopefully 28nm will bring power consumption down considerably. I barely make it through the school day with the stock rom and clock. That and Battery Technology should be a lot better later on.
Northwestern university researchers just outlined a new Li-ion process which will improve battery life tenfold while reducing charging time tenfold. Right in time for these bad boys to hit our pockets.
