Scrapping perfectly good hardware simply because there's no driver for it any more is a real pain in the neck. There are landfill sites full of old printers, scanners, video cards, all sorts of things that worked when they were dumped but... No more drivers.
Technology churn generates sales of shiny new stuff, but it's a drain on people's incomes and it chews through supplies of natural resources that are finite and one day will get scarce. As a long-term plan for the future of our species it's not even good in the short term.
Getting off my soapbox, I can't see Cakewalk picking up hardware drivers where Roland left off because it would mean a huge amount of work for no return and no end in sight for when the job might be finished. Some things, I'm told by Linux coding people, can be reverse-engineered relatively easily. Other things not. I suspect the V controllers might fall in the latter category.
There's also the little matter of how Roland might react to another company, now owned by a competitor called Gibson, reverse engineering Roland hardware or software.
Personally I'd rather Cakewalk put some work into a custom tablet touch-screen control surface that worked on all the current major tablet operating systems. But only after deciding either to sort out ACT, which has needed updating and refining for years or to drop ACT and come up with something better that ties into Sonar's control surface functions.
