CSI is irrelevant for LGA1160 chips. Whatever they use CSI or a new name for the DMI to the southbridge doesnt matter. The old DMI was basicly a modified PCIe link at 2GB/sec.

Unlike A64, Nehalem desktops chips dont need a fast HT/CSI link to a PCIe northbridge host. Because the bandwidth demanding PCIe is ondie on the CPU.

The only thing left is SATA, sound, USB, network and such on the Ibexpeak. But I expect it to be a CSI link. Or a DMIv2(PCIe 2.0 (4GB/sec)) link. Since the value will also have to be able to carry the signals from the GPU for further distribution.
