I believe the accessories are still compatible but there is not a way to plug anything into the new console. I read somewhere that you can use the old console on the new station though.
If your console is okay, you can just buy the sensor suite. Look for 6322, 6323, 6327 or 6328, depending on your requirement level.
Alternatively, you can just replace the sensors on you current VP2. I recently swapped out the old tipping bucket for the newer single bucket rain gauge and the AeroCone. These newer items fit straight onto the older rain gauge base with no problems.
I don’t like the way Davis have joined the other makes and you HAVE TO upload your data to them to be able to use it for yourself. It’s my data and I want to choose how it’s used. I’m going to keep my VP2 going as long as they sell the spares for it. I’ll also be collecting spares, like consoles, if I see any for a good price.
