Some of the Apple ThunderBolt 2 docks have seen port changes and enclosure redesigns as they've been revised. Depending on whether the new docks are from Belkin, Matrox, ElGato, OWC or others - you may or may no longer have FireWire 800 or eSATA connectors. Higher power USB 3.0 ports may be offered to better support charging high-demand USB devices like Apple iPad tablets. Others have shifted from DVI to HDMI as the supported video out as vendors strive to match their docking hardware with the kinds of I/O interfaces most currently in demand.
It's important to note though that Apple's implementation is just the 1st revision of the USB 3.1 standard. Rev 1 means any new devices connected to it will still operate at USB 3.0's 5Gbps speed. It won't be until full USB 3.1 SuperSpeed+ (Plus) chipsets are used in future Macs that the data transfer rates will bump up to SS+ 10Gbps speeds - and on a par with 1st generation Apple ThunderBolt devices.
In a way, that's okay. Very few Apple computer peripherals need or can even come close to maxing out a 5Gbps USB connection anyway. Really, only multi-drive RAID storage arrays and 4K video displays need that kind of bandwidth. (And in particular - PCIe based solid-state drive arrays.) As such, expect the industry-wide rollout of SuperSpeed+ to 10Gbps to be a slow one. It remains to be seen if, how and when Apple implements it across their MacBook and desktop line in the year ahead.

In the past quarter - which spans the holiday shopping season - Apple sold a record-breaking 5.4 million Mac systems. That's great for both MacGizmoGuy's like me - and consumers like you. The market trend towards dominance in cell-phones and computing tablets has been somewhat detrimental to the shrinking share of the pie for conventional desktop computer peripherals and Mac accessories. Although there's some cross-over, many gadget and gizmo manufacturers are focusing ever-more R&D dollars towards mobile computing products geared for handhelds.
With Apple on trajectory to likely sell 20+ million Macs, 5 or more million each quarter. 4+ million of those will be MacBooks. That helps insure a reasonably healthy market for conventional computing peripherals designed especially for Mac.
