Henry Cavill's Black Superman Teaser

Recently, Henry Cavill posted a teaser of the black Superman outfit on Instagram and I don't think he's getting ready for an early Halloween party...it is most likely going to be seen in Justice League Part One, which is due to be released sometime in 2017.

So what does this mean? It means that Superman is going to return after being resurrected. How he is being resurrected; we don't know. In the comics he is put in the 'Regeneration Matrix' in his Fortress of Solitude, but that seems unlikely as he ended up in a coffin of sorts at the end of Batman vs Superman. And what else does it mean, I here you ask? It means we may see Henry Cavill's Superman with long hair...
