Back to the Future Day has already delivered in a major way, but there's still more to come. One of the biggest anniversary events, the official unveiling of the self-lacing 2015 Nike Mag sneaker, is rumored to be going down tonight.

As you may recall, Michael J. Fox debuted the 2011 version during an episode of Late Show with David Letterman. Now, it looks like we may be getting another late night debut, as he's slated for an appearance on on tonight's episode of Jimmy Kimmel Live!.

A Tweet from Kimmel hints at "something very special," which all but confirms the hugely anticipated unveiling. Set that DVR now, you won't want to miss this.

Meanwhile, the Michael J. Fox Foundation has let loose the very first glimpse at the 2015 Mag. 

Which was later followed by this clip of Michael J. Fox testing out the power lacing, which looks every bit as cool as you'd expect and should be more than enough to get 'heads excited for the 2016 release. Check out the video below and be sure to tune in to Jimmy Kimmel Live! for the full unveiling.
