It turns out Kobik, the sentient Cosmic Cube in the service of the Red Skull has been keeping an untarnished, evil-free version of Captain America inside its consciousness. That's right, those fan theories that Kobik had re-written Steve Rogers' memories and altered reality itself were not too far off the mark.
However, there aren't two seperate, physical Steve Rogers (yet) as the one currently leading Hydra is in Cap's original body while the Rogers inside Kobik is currently nothing more than the memories of pre-Hydra Cap.
Still, with the familiar Captain America stored away inside Kobik's consciousness, it's only a matter of time before he breaks free and embarks on the Captain America redemption tour that kicks off in Captain America #695, when Mark Waid and Chris Samnee take over the title. Kobik has even went so far as to show the version of Captain America stored inside her memories what his evil doppelganger has been up to. Naturally, he begs to be set free but just before Kobik can do so, she's scared off by someone or something.
Hydra-Cap's reign will come to an end in Secret Empire #10, out August 30th. An extra issue, titled Secret Empire Omega, will also be released the following month on September 13. Captain America #695 will then kick off the Waid and Samnee run on November 1.
