The -E chips have always been released a year to a year and a half after the standard models. Broadwell-E has been announced and looks to be shipping in February or March according to rumors, and Skylake E about a year or so out. The biggest curiosity for me is the lack of the Xeon E3s. Those launched simultaneously with the past few generations of desktops, with nothing so far regarding when/if they're going to be released, other than a mention in the Skylake chipset datasheet that the last four io lanes were skylake only. Edit: Completely forgot about the Xeon D chips. That could be an interesting path to go for the desktop supercomputer route. 32 pcie lanes, and 4-8 cores with hyperthreading. They're not as beefy of a core, but with 10gig-e onboard, could quite possibly fit in the role of GPU router.
