B&W New Diamond Series?


My apologies if this has already been discussed repeatedly but I've been eager to learn more about the new Diamond series coming from Bowers and Wilkins.  Is there any word on a potential release date?  What improvements are rumored?

Classic features of inflation. Consumer panics thinking the longer they wait, the higher the price they will pay. Everyone buys creating shortage and pressure on price continues upward. But wait! Uncle Joe says "inflation will be temporary!". If you can't trust old joe, who can you trust?
Some dealers suggest it’ll take til 2024 for manufacturing to catch up to demand. Sellers market!

I know this is an old thread but I’m in a bit of a quandary. I currently have a pair of 705 s2’s. I have an opportunity to purchase a used pair of 805 D3’s in mint condition locally. Unfortunately, I can’t run an A/B comparison. I’ve heard the D3’s before but not on my system. I’ve heard the 705’s may sound better at lower levels. Don’t know if this is true. Would I be crazy to pass up a pair of black D3’s for $4400?
