It looks like Intel is preparing the 14nm shrink of their current "Haswell" fourth-generation Core processor for the second half of next year. "Broadwell" is what Intel refer to it as, and it looks like we could expect the chipmaker to be concentrating on mobile parts instead of desktop parts this time around.
From the shot above, thanks to VR-Zone, we can see the Core i7 4770 will still be good until the second half of next year. From then, the entire lineup of Core processors will shift to the Haswell refresh, currently known as Broadwell. We can also expect Intel to launch Ivy Bridge-E processors in September of this year.
Haswell-E will bring DDR4 support, and the upcoming U and Y series of mobile CPUs will include SATA 6Gbps and USB 3.0 support.
