More like a low-clocked, high-bit interface for power draw reasons. The GeForce versions of Tesla are usually higher clocked and have higher CUDA Cores and SMXs.

Power Draw is everything for Tesla.

High bit rate = higher power consumption.

We can probably expect perhaps high bit from the big daddy since the 256-bit was a bit limiting.

You never know with Nvidia.

Someone from here linked to the Kepler GK110 technical paper on another thread (can't find the link right now), I read a few pages and can tell you that GK110 has a 384-bit memory bus, so unless along with the disabling of 2 SMXes they also disabled two memory channels, that part at least should still be the same, albeit lower clocked.
