Right now I can listen to the new P25 system on my 996T & 996XT. And I get Fleetnet analog & digital. With EDACS being decommissioned at some point, ProVoice is no longer of interest to me.
Now, Fleetnet's going to be around for a few more years. There may be talk about replacing it at some point, even then it's likely to be a P25 system. But those of us who've been around for a while know it's going to be many years before we see a roll-out. I mean, look at how long the Ottawa P25 roll-out has taken, and it's nowhere near done yet.
At some point there will be the Phase 1 vs Phase 2 discussion for P25, and if Phase 2 comes into play then the older scanners incapable of Phase 2 will be obsolete. That will be the first deciding factor on an upgrade.
But, and this is the biggie, word from many sources is that most or all of the users of the Ottawa P25 will be encrypted. Police for sure, but I'm hearing from people "in the know" that the plan is to make everybody encrypted eventually.
And when the new provincial system eventually rolls around, almost certainly encryption will be a discussion point then too.
So, my attitude is that when I lose the ability to listen to something I really want to listen to, and if there's a scanner upgrade available to get that back, and if there's no indication that this new scanner will become obsolete within a reasonable amount of time (ie. due to encryption), then I'll think about it.
Sorter answer: at this moment I'm not recommending anybody replace an existing scanner right now, if their existing gear can get most of what they want to listen to. And I'm similarly not recommending new enthusiasts buy anything now that may become obsolete in less than a year (ie. don't bother with non-digital scanners).
