Uniden had Paul Opitz. He was a one-man show that could do everything. He passed, rather untimely. So they got someone to volunteer to replace him, who, by his own admission, is no where near a Paul Opitz in terms of his stature with the company. Then someone identified this poor soul as the guy who allegedly runs AirSpy, which may, or may not be true, and if so, may or may not be a conflict of interest.
He created a "list" of some very good recommendations that were made by the folks here in attempts to correct issues with, and improve the operation of the SDS series of scanners. His intentions may have been good, but apparently, not having the clout of a Paul Opitz, the folks at Uniden probably told him, "yeah, yeah, yeah, good, good, good", and that's where it ended.
No firmware updates, no fixes. About four months ago, in some other thread, I called this guy "Joe Bearcat" out, and I very mysteriously lost the privilege of a day's access to posting for my comments. Coincidence?
I posted an apology, which you can easily find, and since that day, I take everything here that Joe Bearcat posts with several grains of salt. Even though he was allegedly "vetted" by someone here on Radio Reference, maybe he sold someone a bill of goods. To me, it doesn't matter anymore. He has remained "in the closet", his last name has only been guessed at, and some pictures of him allegedly appeared on some other site.
So take it for what it's worth. As I pointed out, I believe that Uniden now considers the SDS100 and SDS200 to be "mature" products that continue to sell and operate, more of less, to specification. The addition of any other features will likely be left to some future model(s). And if I were Uniden, I would be absolutely mortified to do any firmware updates for fear of inadvertently screwing something else up with the operation of the radio and incurring more wrath then they already received here and elsewhere.
As for "Joe Bearcat", to his credit, he has given some of the folks here some decent advice on straightening out operational problems that they were having with their units. And it's not really "insider" insight--- others here could have helped just as well. And others did.
If Uniden eventually comes out with any fixes or firmware updates, it not likely because of anything Joe Bearcat was able to accomplish. He's just a guy who likely has a second job, a wife, screaming kids and a barking dog. Paul Opitz was superhuman and did amazing things--- Joe Bearcat is a mere mortal, just like the rest of us. Live and let live.
