Today, Entertainment Weekly "broke the news" and included the cover.

Jim Lee is co-publisher at DC now. Remember, his WildCATS and Gen 13 openly explored lust among the characters, so this is not a surprise.
And what are my feelings on this?
Well, Wonder Woman looks nothing like Kara Zor-El, Supergirl, Superman's cousin that he wants to bang.
Wonder Woman looks nothing like Lois Lane, who it was pointed out (by Jor-El, no less) looks almost exactly like Superman's mom.
In other words, Superman is going to be in a sexual relationship with no incestuous overtones for a change.
I am totally okay with this.
