Yea, I saw that - basically the Boeing 7J7 proposal from 45 years ago (but with the engines moved from the tail to the wing so that the passengers can enjoy that ear splitting sound from the counter-rotating unducted fan).
I give it about the same probability of actually turning into reality as well (as in slim and none). Until someone - somehow - comes up with a solution to the noise generated by counter-rotating unducted fans, they are going to be a non-starter.
The noise generated by the trailing fan slicing through the vortices from the leading fan create a noise that would put an early pure-jet 707 to shame - and being unducted there is no way to attenuate that noise.
