Why hasn’t B&W ever entered the ultra hi-end for speakers?

Being one of the biggest speaker manufacturers in the world and arguably some of best sounding, they have never gone past their 800 series and produced anything beyond that point. Don’t get me wrong, $30k ( 800 D3 ) is expensive and most people wouldn’t be able to afford to pay that much for a pr of speakers even if they wanted to, but in today’s market that really isn’t considered ultra hi-end considering some speakers now days cost close to a million and many in the $50-200k range. You would think with the knowledge they have and for the years they have been around they would go the distance and build 
beyond the 800 series?
