They write that is can be connected via TB and that has some USB3&2 ports... but they do not seem to come from the TB controller, do they ? It would be great , though.
It's not clear. But looking at the photo of the back, there's what appears to be a pair of a USB 2 ports, a USB 3 port and a blue square B-type port which would leave me to believe it's not acting as a TB display with USB over TB, but just has a built in USB hub. Although maybe it can work both ways... USB over TB if connected to the computer via TB, or a simple USB hub if connected to the computer via display port (requiring an additional cable for the USB hub). We'll have to wait and see.
