So, in the final analysis, it wasn't a hoax nor was it a leak of a finished/nearly finished product whose release was imminent.
It was an unintentional, unauthorized leak of a product concept.
One thing is certain, though: Uniden is thinking ahead and hasn't abandoned the consumer scanner market. At least not yet. I do hope that the Uniden folks have looked this thread over and have used it as feedback on the SDS100 concept.
I think one other thing is certain: You ain't ever gonna see that scanner.
Just like Detroit's concept cars, those cars never make it to market.
