USB DAC and/or Musical Servers with USB 3.0 port?

Does anybody know if audio manufacturers moved already or near release of equipment(s) with USB 3.0? Sure, they need different motherboard etc but hi-res files e.g. 24/176 (Reference Recordings) can be played in real time and EASY.

APL HiFi ?
Playback Design ?
EMM ?
etc

If you build your own music server then its not a problem to get right equipment... I only have no idea if JRiver and other similar software can take advantage of the UBS 3.0 hardware?

Thank you
