No this isn't a joke. Apparently Nike are to release the same brand of self-lacing trainer that Marty McFly used in Back To The Future.
Last time I checked this wasn't 2015 so I think it's fair to say that Nike are way ahead of the game. Who cares though when you could own a pair of trainers this cool!
Yes they will incorporate the self lacing style that was shown, yes they will be almost exact replicas and yes they will probably cost you more than you earn in a year.
Movie merchandising seems to be on the up, I myself am addicted to movie themed t-shirts, so for me this is a pretty cool way to go with the idea.
