Jake Dyson looks to be positioning himself as heir to his father’s legacy. He’s added a wall-mounted Motorlight to compliment the free-standing version and is busy working on a third version.

Will Dyson (Senior) one day launch a coffee machine? Interesting patent filing here, which describes a method to simplify the internal working of such a machine, so that two ingredient hoppers can be operated by a single motor :-

in turn, would there be any value in having coffee beans grounded by a Dyson Digital Motor at 100,000 rpm? Maybe!
There's no obvious reference to floor / laundry care in the description, but perhaps it could be applied.
The Dyson AirBlade web site has had a recent overhaul including a great video with John Churchill, who is credited with having the initial idea for the product.
