Next year will probably be the banner year for dual-core phones, but it's possible that 2012 will be the banner year for quad-core phones. Interestingly, most folks assume that dual-core and quad-core chips in phones will kill battery life, but actually if you dig deeper into the technology you find that moving to multi-core designs actually improves battery life. This is because the 'multi-brained' chips can process more information at lower clock speeds, and lower clock speeds means less power consumption.
