There have been Day of the Dead themed sneakers released, and they've been a somewhat simliar colorway (mango-orange/grey/black). They also had skulls on them. The dates are still off though. DOTD is in Oct, and Cinco is of course May.
Who knows...maybe the 12 is going to release earlier now that Kobe has officially decided to retire, and the 12's cycle will start earlier this year in the Fall. If that was the case...maybe they're releasing models that were originally intended to come out later in the year (i.e..maybe this one was originally supposed to be in Oct), and they're all getting pushed up. Look at how many are releasing in quick succession this month. There's one on the 14th, one on the 19th, and one I believe is on the 25th. 3 releases in 12 days.
