Has Lexus Created A "Hoverboard"?

I'm still not sure what to make of this yet...

Lexus has created a promo video for what they are claiming is to be their own version of a "hoverboard."  It looks cool and stylish, and inside it has liquid nitrogen-cooled superconductors and permanent magnets (which explains the mist coming from the board), and will only work over metal.  Lexus has admitted that the skate park show was done with metal inlaid to the set when they filmed this promo video.  The video does not, however, show the skater actually getting onto the board and riding it around.  Check out the video below:

If they are even one step closer to making this a reality, then I think that it's pretty cool, but until we actually develop tech that gives us "antigravity" capability, then everything that they tout as a "hoverboard" is really only a gimmick that uses magnets and metal.  Look, I get it, we still have a long way to go in this field, but if everything has an equal and opposite reaction, then if there's gravity, there also has to be antigravity, right?  Makes sense as far as the laws of physics go.  Why is it being so difficult to explain, or for that matter, create and duplicate?  

I'm not trying to pooh-pooh there product here.  It is actually pretty cool looking.  I was just hoping for the real deal, that's all.  I know, I ask too much.
