4 channels on thunderbolt is really a waste.  Also the gimmickry of the website does not instill much trust in the quality of the device.  No mention of the preamp/converter quality or specs, only a misleading claim that thunderbolt is "faster."  I believe MOTU and Apogee are also delving into the thunderbolt arena also.  RME's USB3 box can handle more I/O than just about anyone could ever use and it is more universal with great drivers.
