That's my suspicion. My feeling is that Uniden has no intention of offering NXDN for the HP series; they're holding it in reserve for the next generation of scanners, yet to be announced.Selloff? New NXDN hardware coming?
It may be an inventory blowout prior to the release of new scanners models. Seems logical.
