Oh c'mon, not like enterprises wouldn't want to get a little piece of the pie, so they'd give fundings and such. Slowly the hoverboard thingy would progress, and even maybe grow into the hover-bikes and hover-cars you so much want, after all, if they manage to make somehing that can lift light stuff, soon they'll want something that can lift heavy stuff- THEN SCIENCE!
C'mon, people spend MILLIONS making cars, something already invented.
Hoverboards are something extremely new, so don't expect it to be any time for ages.
