Harbeths new Extented Defination

Harbeth is making changes to their existing speaker line and calling it the Extented Defination line.  Anyone here their  new Extented Defination speakers?
From what I read, Harbeth is using the term "XD" as an upgrade version their existing line of speakers.  Changes focus on a different crossover (similar to their anniversary versions) and new finishes.
I wonder what Krell with say about "XD".  Of course its on speakers and not amplifiers.  Look for a change to another name.
