Usually, this wouldn't mean much because Intel don't plan on baking DDR4 support into their products this side of 2014. The first to receive DDR4 will be server chipsets such as Haswell-EX. Desktop and mobile would receive DDR4 in 2015 with Broadwell, a 14nm die-shrink of Haswell. But... there are now some seriously big players who want some high-speed DDR4 goodness, AMD, NVIDIA, Qualcomm and TI. I'm sure this will grow in between now and 2013, too.
