Ivy Bridge-E will be an upscale of Ivy Bridge. Similar to Sandy Bridge-E, the silicon will feature up to eight cores and 20 MB L3 cache. In its Core i7 avatar, however, the chip will be configured with no more than six cores, and no more than 15 MB L3 cache. The new chip will introduce IPC improvements, PCI-Express Gen 3.0 certified root complex (one which NVIDIA will approve of), higher CPU core clock speeds, and support for faster memory.
TDP could be the only reason Intel isn't willing to unlock cores 7 and 8 on client processors. Eight core, 20 MB LLC-laden Xeon E5 models based on today's 32 nm silicon, with 130W TDP, barely manage to scrape the 3.00 GHz mark. Given that, the prospects for Ivy Bridge-E client CPUs to run with all cores and LLC enabled, and yet deliver higher clock speeds than predecessors were always going to be low.

Not sure if this has been stated before but I thought I would share anyways.
