My big question is about the number of devices one can connect. The article says you can daisy-chain six, but also mentions hubs. So does that mean that each of those six could be a hub and thus the total number of TB devices would be greater?
As a corollary, I assume that a USB or Firewire hub would count as a single device. So could I connect (for example) 1 monitor, 1 RAID, 1 HD camera, 2 USB hubs (with say 4 devices each) and a firewire hub (with 4 devices)? Or is 6 the total max number of devices, no matter how they are connected?
I suspect this is a misreading of early information and that the limitation is higher.
Display Port supports daisy chaining up to 6 monitors off a single connector. As such, Thunderbolt, when directly driving non-Thunderbolt displays, will have the same limitation.
Once you're out of the Thunderbolt realm (i.e. other side of a Thunderbolt to USB/firewire/SATA/... adapter), any limitations are outside the scope of Thunderbolt anyway.
Note that Display Port supports tunneling USB, so theoretically chip designers could create both USB via Display Port over Thunderbolt hardware and USB via PCIe over Thunderbolt hardware. Since USB over Display Port is a published VESA standard that's been out there for a while, I suspect the market will go that way.
