The good thing about Davis, they enhance the product with tweaks rather than wholesale changes, like improving the temperature-humidity sensor, adding bird spikes to the rain collector, etc., but the VP2 is dated technology, particularly its related WeatherLink software that looks like it was written for Windows 95.
Well of course Davis may well have concluded that updating WL (for Windows) is simply not a priority for them and they would rather spend their development dollars somewhere else. WL is still a good workhouse package, if cosmetically dated. But it's not as if there aren't plenty of other compatible packages like Cumulus, WD etc and very possibly Davis have decided that they don't need to compete in that space and that the future is in the cloud. We'll have to see what the much-delayed upgrade to weatherlink.com actually delivers when it arrives.
(Of course I could be completely wrong and maybe a brand new version of WLfW will be released next week, but I kind of doubt it - I rather think that Davis consider WLfW as a dated approach to presenting weather data and that what comes next will use different technologies like the cloud.)
If I had to put money on anything I'd suggest that the ISS will stay much as it is (though it would be nice to have an easier way of separating rain gauge and radiation shield and a better calibrated rain gauge). The big unknown is whether the wireless technology makes a jump to something else like Zigbee, in which case that might be associated with a complete rethink of the console/logger unit.
But just to repeat, we've still heard nothing, not even early rumours, of a VP3 so I doubt that it will appear in 2017, though might conceivably know more after the Madrid AWS trade show in about 4 weeks' time.
