RS was on the ropes when the Pro-668 hit the market. This was no secret. If you paid full retail for a Pro-668, well, I feel bad for you, but again you must have been either living under a rock or an incurable optimist. I expect that most of us bought our 668's at a deep discount, as I did. For $125 I got a digital trunking scanner at least as good as the PSR-800 at its zenith. And because that radio had no serious bugs or issues (other than LSM) and supported p.2, that was "good enough." I always viewed future support as something that would be nice to have, but probably wasn't likely, considering the RS corporate health situation. Whistler does not build radios or develop updates for free; they are in business to make a profit. We cannot expect them to pick up the slack here. RS must get to work and make it happen, and I imagine that would not only involve monetary compensation for the updates, but also back payment for ??? many RS-branded products Whistler built but never got paid for.
I would also make the point that when most of us got our Pro-668's (and WS-1080/WS-1095's, and for that matter 436/536hp's), there had been zip, zero, nada talk of any of these radios ever supporting DMR, TRBO, NXDN, or anything else besides P25.
