atleast the cables wouldnt fall out and detone the whole place.
latency doesnt matter anyway 
on a second thought, why not just set your audiodevice up with an IP-adress and let both your computers stream the soundsignal through a GB-switch, or even better WLAN? firewall would have a whole new meaning

NO!! I refuse to go back to rs232. That is such a piece of shit. You think you've got problems now? Try using rs232. mmmmm, 20kbps, that'll work nice with several channels of audio and midi.
Well, I spose we all use a latency of 2408 anyway so it would probably work 
I've done a bit more research and found very mixed signals about FW.
Some manufacturers are announcing new FW products and others are discontinuing them or changing them to USB 2.
There is no information on USB products yet.
Here is the specs of USB 3.0 - Basically looks good and is comparable in speed to PCIe, can support a larger power draw (Mamps), and requires less power (v) as a minimum for the device to function.
Features
* A new major feature is the SuperSpeed bus, which provides a fourth transfer mode at 5 Gbit/s. The raw throughput is 500 MByte/s, and the specification considers it reasonable to achieve 400 MByte/s or more after protocol overhead.
* USB 3.0 receptacles are compatible with USB 2.0 device plugs for the respective physical form factors. However, only USB 3.0 Standard-B receptacles can accept USB 3.0 Standard-B device plugs.
* When operating in SuperSpeed mode, dual-simplex signaling occurs over 2 differential pairs separate from the non-SuperSpeed differential pair. This results in USB 3.0 cables containing 2 wires for power and ground, 2 wires for non-SuperSpeed data, and 4 wires for SuperSpeed data.
* SuperSpeed establishes a communications pipe between the host and each device, in a host-directed protocol. In contrast, USB 2.0 broadcasts packet traffic to all devices.
* USB 3.0 extends the bulk transfer type in SuperSpeed with Streams. This extension allows a host and device to create and transfer multiple streams of data through a single bulk pipe.
* New power management features include support of idle, sleep and suspend states, as well as Link-, Device-, and Function-level power management.
* The bus power spec has been increased so that a unit load is 150mA (+50% over USB 2.0). An unconfigured device can still draw only 1 unit load, but a configured device can draw up to 6 unit loads (900mA, an 80% increase over USB 2.0). Minimum device operating voltage is dropped from 4.4V to 4V.
* USB 3.0 does not define cable assembly lengths, except that it can be of any length as long as it meets all the requirements defined in the specification. However, electronicdesign.com estimates cables will be limited to 3 m at SuperSpeed.
* Technology is similar to a single channel (1x) of PCI Express 2.0 (5-Gbit/s). It uses 8B10B encoding, linear feedback shift register (LFSR) scrambling for data, spread spectrum. It forces receivers to use low frequency periodic signaling (LFPS), dynamic equalization, and training sequences to ensure fast signal locking.
Availability
Consumer products are expected to become available in 2010.[37] Commercial controllers are expected to enter into volume production no later than the first quarter of 2010.[38]
Windows 7 drivers are under development but no public releases have been made available as of April 2009. The Linux Kernel supports USB 3.0 as of version 2.6.30.
