@AA1ZA: Davis simply do not release any detailed information about the breakdown of units sold, so any aggregate figures worldwide are impossible to calculate. I can offer a UK perspective, but how representative that is of the wider world can only be a guess. But two broad comments:
It's not just agriculture vs hobbyists; there are many other market sectors too, like education, outdoor activity clubs of all sorts where weather readings are important (sailing clubs, motor racing, small airfields etc etc), academic and commercial research or services (not focused on high-end weather, but eg for ecological studies or ambient noise surveys where weather during the trial is an important variable) and many others. For the non-hobbyist groups across the board things like having a colour console or eg humidity accuracy typically score pretty low, indeed most agriculture systems now are EM and so don't (can't) even involve a console.
I don't have exact figures by category at my fingertips, but if I had to guestimate by value (ie rather than units sold) I'd say:
Hobbyists: 25%
Other non-agriculture applications: 35%
Agriculture: 40%
(Remember that a lot of private individuals will simply buy Vues (for reasons of budget or they simply don't need more), whereas a typical EM station order might be $3K value.)
On VP2-type developments, I think there will be new products here but, as is often said, Davis are not a large company and their development resource has to focus most of its efforts on a couple of major projects at most at any one time. In recent years these have been EM and the wl.com 2.0 platform. But I don't think that Davis will leave their traditional VP2 products in their present state of development indefinitely, they've just had to wait their turn while the focus has been elsewhere. So I won't be surprised to hear some announcements at some point in the next year or two, but exactly when who knows? But given the effort that's gone into wl.com 2.0 then I suspect that a major part of future data handling/present will make use of that toolbox.
