1) Sorry for any confusion... If I implied TB2 would be included to support the monitor's 4K capability, I didn't mean too. I meant it would replace the current FW800 port. So where the current ACD has one FW800 and one TB, the next will have 2 TB2.
2) I would expect the next ACD to match the ports on the MP otherwise what point is there for MP buyers to buy one? The new MP has TB2 and USB3 which is why I predict the ACD will match these ports. The current ACD is woefully outdated. I can't see them pushing out an update with the same TB1 hub. Eventually all Macs next year will get TB2, but Apple needs a monitor to sell with the MP or it might as well just exit that business like it did with other peripherals. (Maybe that is the plan too, but I think it needs a monitor if just for show).
Sorry let me clear up my point as well. I switched on you halfway through and started talking about TB2 on the rMBP rather than the ACD. Totally agree they will likely put TB2 and USB3 on the refreshed 4K ACD, but what I was saying is that TB2 isn't a requirement for the next rMBP upgrade.
