I haven't seen any reports from anybody who has actually seen the Rodelink yet.
The Rodelink and the Audio Technica System 10 are probably comparable as they use 2.4 GHz wi-fi technology and full digital design.
And the new Sennheiser D1 system appears to be in the same family of 2.4 GHz WiFi-like technology.
OTOH, The Sony UWPD is more of a traditional UHF analog system with a bit of digital compression thrown in.
But the transmission and reception are traditional analog technology as we have been using for decades.
Note that there is a discussion of the Sony system here on this forum already.
