Well if you are interested in developments at the high end, ATC have developed their own tweeter (available since about a year or two) Similar to their legendary 3" dome mid range, this tweeter has a double spider for stability and no ferrofluid. It took about ten years to develop (no doubt tested in various major studios before a general release to market)
The driver integration on their designs is obviously superb as ATC now control everything in house including the active crossovers and discrete amplifier dedicated to each driver.
With regard to the lack of discussion on high end speakers I think it is clear that most Audiogoners primarily invest in and prioritize component electronics, cables, interconnects and all manner of power conditioners and other tweaks such as reclocking devices. I don't understand this approach as I believe speakers to actually be the most important part of any audio system.
