Not really. There are 6 TB ports. Who cares if just one of them are tagged with a TB v1 chain of devices? You'd still have 2-5x as many TB v2 ports than any other system out right now.
Personally, I'd rather have two of the Monoprice displays for less than the cost of one ATD whose ports are a lower spec than what the nMP offers.
I'm sure there are USB 2.0 devices. ( keyboard , mouse , dongle software/locks , etc. etc.) that most folks can use to populate those USB 2.0 sockets. Segregating USB 3.0 and USB 2.0 devices onto different USB controllers is a good thing; not a bad one. The older docking station/display can be put to use doing exactly that.
Sure folks with 5-6 USB 3.0 devices would need a better docking station display, but how big of a market is that? Folks crying the blues about not enough USB ports on Macs typically have gobs of legacy stuff they want directly attached; not the bleeding edge stuff.
It the docking station/display would have more long term viability if it had 3 USB 3.0 , FW 800 , Ethernet ports but the current on isn't that big of a deal on a Mac Pro.
On a 1 port MBA there is a difference. Those laptop systems with just one (maybe two) TB ports. Right now though, all TB v2 capable Mac systems have at least 2 (which reduces daisy chain pressure). The Mac Pro is in another whole different zip code from the rest of the line up.
So you're basically saying that having 3x USB2.0 and 1xTB1 daisy chain port built in to the ATD is worth $540? Because that's the price difference and advantage the ATD has over the non-Thunderbolt display I linked above.
Even the Sonnet TB docks are (going to be) cheaper than that AND provide even more functionality. Not only that, you end up decoupling the dock from the display. That's a win.

For the money, the ATD just isn't the value that it used to be and, based on what's available or will be available soon, it is a downgrade.
