Back to the Future producer Frank Marshall set off a flurry of speculation today when he tweeted:

"Something big is coming soon. Can't say anything yet. No one should know too much about their own destiny. #BTTF"

Great Scott!  What could it be?  A sequel?  A remake?  Luckily, it's nothing quite so drastic as anything my imagination came up with, but something pretty neat nonetheless.  Nike sounds ready to unveil the self-lacing sneakers they patented back in August 2010.  Nike sent out an invitation to a very lucky few for an event tomorrow night that promises "an unveiling that could change the course of time."  The contents of the package also included the futuristic glasses Doc Brown sported in Back to the Future II as thinly veiled clue about what to expect.  To confirm, Marshall followed up with a tweeted link to a new commercial titled "McFly's Closet," populated by hundreds of pairs of the shoes.  Watch the clip after the jump.

Sweeeeeeeeeeeeeet.

Sneaker bloggers Nice Kicks [via Badass Digest] kindly shared pictures of the glasses and the invitation.

Finally, here's the scene where Marty McFly tries on the sneakers in the year 2015.  Starting tomorrow night, you can look that cool!
