I had some hands on with the RX and snapped a few pictures as well. I am definitely excited to get one and hope to hang around the day after Production Nationals to shoot CO Nats. I am actually shooting a CO match tonight with a P320 and a DeltaPoint in an attempt to at least get classified in CO.
Everything is waiting on the release of the Romeo1, which is still scheduled for later next month. As soon as the factory gets a hold of them then you can expect Full Size and Compact RX to start rolling out. The priority will be full guns first. Exchange kits will likely happen but not until later. A P320 Target is also possible but, again, not until later. If I wanted to shoot a P320 Target in CO for Nationals this year I would plan on buying a Target and having the slide milled for a Romeo. That is only my assumption there, no inside knowledge on my part about the timing of a P320 Target RX. I just think they need to get some of the already announced stuff out the door before focusing on new variants.
