When?

 

[naynay]

Will this benefit from seperating the Power and Data lines on the usb input and use a seperate power source for the 5 volt?

This has since been updated to PAW D3: http://lotoo.cn/english/Accessories/PAW_D3/

 

[naynay]

That looks like it is more catered to the wireless Lotoo Teleport Protocol. It also looks cheaper than the PAW D2 and takes away the XLR output.
