That's exactly what's I feel is so wrong in the industry. Intel isn't pushing out new technologies and therefore "standards" into the market. Development is stalled to a minimum innovation, maximum profit situation.

And more generally, Intel just isn't interested in equipping anything with much bandwidth except in the high-end server market. Their current mainstream consumer/low-end server/workstation platform has 20 PCIe 3.0 lanes direct from the CPU (but only 16 are enabled for the consumer chips), and 4 PCIe 2.0 lanes (20Gbps total) for the chipset and all the other peripherals to share. A single one of these new Thunderbolt ports could monopolize all of the peripheral device bandwidth available through Intel's current CPU socket. Copying a file from one SSD to another SSD uses more than half the available bandwidth. It used to be that a desktop system had the advantage of being upgradeable and expandable, but now you often need to get a new CPU+motherboard in order for new peripherals to run at full speed.

  It seems obvious that Broadwell will probably have more PCIe bandwidth so that it can feed Thunderbolt 2.0 plus some other stuff.

  PCI Express 3.0 is 1GB/s aka 8Gb/s per lane, you seem to have got confused between GB/s and Gb/s. Three lanes would give you more than you need for a new thunderbolt port. Also if you take x79 which is a consumer platform it has 40 PCI Express 3.0 lanes which would be enough for 16 of the new thunderbolt ports.

    X79/LGA2011 is way too expensive to be considered as a mainstream option in the consumer marketplace, and isn't even an automatic choice when shopping for a workstation (since the Xeon E3s are so cheap). On LGA1155, the connection between the CPU and GPU is now PCIe 3.0, but the connection to the chipset and other peripherals is still running at PCIe 2.0 speeds and is only 4 lanes wide. Unless you have a motherboard that is specifically designed to rob PCIe lanes from the GPU, all USB 3.0 and SATA 3 ports and gigE ports are sharing that 20Gbps link from chipset to CPU.
