SATA III - Can easily be added with a PCIe card
The X79 chipset has some SATA III ports built-in (14 SATA ports total, 10 of them at 6.0Gb/s).
Thunderbolt isn't going to happen as the X79 chipset does not support thunderbolt, so I don't see this happening at all..
The X79 doesn't include TB, but it's possible a TB chip could be added, so long as a means of getting a DisplayPort signal to the chip is implemented in order to keep Intel happy (i.e. usage agreement in order to prevent initial confusion over data only or data + video configurations = improves the chances TB will be adopted by users).
Hellhamer made a point that all one has to do is add ESATA which is going to be twice as fast as thunderbolt.
I'm not sure if there was a misunderstanding or something else, but eSATA on a 6.0Gb/s controller is only good for ~ 550MB/s for a single port. Faster is possible via one disk per port in a RAID configuration, but not as a single port (may be the source of the confusion).
As a single port, TB is faster.
Using PCIe slots can produce faster solutions than TB as well (i.e. hardware RAID card + sufficient number of disks for example).
And FINALLY.. memory - 1600 mhz DDR3 memory which isn't that much faster than 1333 mhz. Unless you have a use for weather related software, or very heavy scientific software, you won't notice much of a difference between 1333 DDR3 which you and I have now versus 1600 DDR3. So, really the only benefit I see is onboard SATA III and thats all.
Whether or not a user can utilize all the system cores for a single software application depends on how it's written (true n core multi-threaded or not). Same goes for memory (the application has to be capable of utilizing the bandwidth).
Unfortunately, such software is fairly rare right now (what you mentioned can, but it's not exclusive to those areas).
Some enthusiasts may care about that, but enterprise doesn't and they are the far bigger customer for LGA 2011 processors. One of the big reasons Intel have switched to releasing consumer processors first is so enterprise can benefit from real world testing and refinements of the platform.
Another major reason consumer parts ship first (probably bigger from Intel's POV), is that they're easier and faster to get shipped = generate an income while completing the enterprise versions (design + testing of LGA1155 = shorter cycle than the LGA1355 or LGA2011 parts).
