If its another Unimog, then the old saying “ whats old is new again “ applies.
Unimogs are probably the most capable Swiss Army knife vehicle ever built, they’ve been around forever. You can do almost anything with one of them.
I don’t think a 4x2 or tracked dump truck is the market Kubota is looking to compete in. I think what is being proposed is an over the road, larger version of the Toolcat with a larger dump bed.
IMO, it would be worth buying IF it could allow me to push a truck AND another piece down the road. If the Kubota all purpose vehicle could allow me to get rid of one tractor, one skid steer, etc AND a 4wd pickup truck, I’d do it.
