I specifically asked that from my rep, and he didn't have a list price, but he expects it will be similar to the other P25 phase 2 gear. There isn't any licensing associated with NXDN as there is with P25 from DVSI, so it doesn't add to the external costs. It would be smart of Kenwood to keep it this way.
The way I see it, this type of radio makes it possible to save money on these larger common systems. NexEdge trunking can be used for nonpublic safety use, and P25 for public safety.
I have a 5 channel NexEdge trunked system at work, and we have all our "public works" type users on it. Those guys don't need a p25 radio by any stretch of the imagination. Our PD could go with these radios and still have interoperability with the public works folks, if needed (rarely), use analog, and still have P25 for mutual aid. Even if the radio costs a bit more, the amount of money we'd be saving by not having to purchase P25 radios for a bunch of people that don't need them makes financial sense. From what I've heard, this is how Kenwood sees it. Logical cost savings. No reason to force everyone onto the highest common denominator system because of a perceived need for interoperability.
In all my experience, the number of times that a police officer needs to talk to a public works person is slim to none, there are certainly other ways around that.
