It seems to me that based upon the silhouette of the "Third Kryptonian" on the cover of the upcoming Superman #670, it looks like a certain female that was shown in Action Comics #850...when Brianiac 5's chronexus ruptures, showing glimpses of what may be future events. The page I'm referring to shows what seems to be a Kryptonian city, with a volcano in the background. There are, what appears to be, Kryptonians on the ground and in the sky. Supergirl is standing amongst the Kryptonians, while Superman hovers, uttering, "It's...It's beautiful...I can barely believe it..."
One of the women (with a face looking similar to a young Dr. McCoy from Star Trek), with short hair (and holding a stogie?) is wearing the same type of vest jacket as suggested by the silhouette drawing on the cover of Superman #670.
What's also interesting can be found in the solicits and images themselves...

"...makes a desperate last stand against a deadly threat to every Kryptonian in the universe!" Every Kryptonian in the universe? Also, "...a shattering turning point for a key concept in the Superman mythos"?
Obviously, Superman is not alone since he has the likes of Supergirl, Chris Kent, Krypto, and alternate Kryptonian Power Girl...but are we now subject to witnessing the birth (or rebirth) of the New Krypton concept, where truly the Kryptonian race lives on? And, what would this mean for Superman?
