Yes, Wireless USB could be the most popular technology in the future!
The data rate of Zigbee is up to 250Kbps and it is usually used in Home and Commerce, such as heat supplying, air conditioning and lighting control.
The data rate of Bluetooth is up to12Mbps and it is mainly used for audio transfer or control of PC peripherals, Earphones, Cell Phones and PDAs at a low data rate.
Wireless USB can reach the speed of up to 480 Mbps with distances up to 3 meters, and up to 110 Mbps over ten meters. It is suitable for the applications of video and data transmission at high speed. I think it will be first used in portable devices such as Cell Phone, PDA, DSC, DVR and other Storage Devices.
So, Wireless USB will not threat Zigbee, but Bluetooth is likely to be replaced gradually by Wireless USB in coming days.
I'm not so sure. We already have cell phones, PDAs etc with WiFi, so I can't see why they would also need to have wireless USB for media transfer, unless there is a significant cost/power reduction. This is unlikely to happen with a mature technology like WiFi. I know the physical presence to a transmitter could be a problem, but in my opinion most transfers happen in the home/office/public places where WiFi is present.
Even this problem could be helped with WiMAX, or any other type of MAN, relegating WUSB to point to point transfer. It should be interesting to watch and see how things turn out
WUSB and WiFi respectively concentrate on different applications.
WUSB can work at 480Mbps which is greatly faster than WiFi. For the point to point transfer, I think WUSB will be prevalent in the future as long as there is a resonable cost/power ratio. For example, the transfer of big files such as multimedia between cell phone and computer will be the most common application of WUSB in the beginning; it can be the wireless connetion standard that take the place of the current USB wires.
WiFi is mainly used for networking communications, such as surfing on Internet throgh LAN using Wifi as the communication protocol.
WiFi stress on network exploring, while WUSB stress on data transfer.

Thanks for your reply, it does seem a fascinating subject. I was thinking of applications such as streaming video, for example from a PC to a TV, or a DVD player to a TV. For BlueRay the data rate is around 54Mbit/s, which should be handled by 802.11n/s. On your point about mobile phone transfer, many new phones already incorporate WiFi, and I can't see a lot of benefift in incorporating new technology into phones which already have the technology in place to do that job, albeit a little slower. That's unless you were downloading the full contents of your 15GB iPhone. But in general, I don't think many users would see too much of a difference for the extra expenditure.
However, I can see WUSB being used in office environments, especially new developments, for connecting to printers/scanners.But then the range may be an issue depending on the size of office.
