First of all, welcome to the RR forums Alex, and specifically here to the AOR group. There are some amazing folks here that can help answer practically any question you have about the DV1 and its operation.
You are quite right that the DV1, which was introduced last year, does not do P25 Phase 2. It does Phase 1 and those other modes such as DMR, D-Star and others which are used by both amateur radio operators, businesses, etc.
So the big question is when and if P25 Phase 2 will become available. Based on the best information that I have, along with information compiled from other sources, it would appear the sometime in March (next month), AOR is going to focus on attempting to provide that mode via a firmware upgrade. Whether they will actually be able to do that without making some hardware modifications to the receiver are uncertain at this time. So one way or another, there are no guarantees.
Nor is there any guarantee that if this cannot be done via a firmware upgrade, whether AOR will provide a hardware modification to exisiting users who would likely be interested. If they do, this would likely be something you would have to pay to have done at one of their facilities.
Incidentally, I assume you do not have the radio yet. Make sure you read as many of the posts here on the forums about the radio. If you are in the states, you'll want to look at the posts involving repair issues for radios purchased from dealers abroad.
My experience with the radio itself was very good. But yes, for folks here in the states, where use of P25 seems to be more significant than in Europe or Asia, P25 Phase 2 would be a very welcome addition.
