Spoilers ahead for this week's Heroes in Crisis #3.
Following the release of Heroes in Crisis #3 this week, DC has amended the solicitation text for November 28's Heroes in Crisis #3 - bringing up the notion that Sanctuary, the superhero hospital at the center of the DC event, is operated by an artificial intelligence that may have gone rogue.
"Tragedies deepen as more secrets behind the 'superhero hospital' called Sanctuary are revealed! What compelled Batman, Superman and Wonder Woman to create it in the first place? How was it built? And if the hospital truly is alive via A.I., who - or what - is the brain of 'Sanctuary?'" reads DCComics.com's updated description of the issue. "Another layer peeled back in the biggest mystery woven through the entire DC Universe."
Tom King has previously stated that Sanctuary was build using Kryptonian technology, and this week's Heroes in Crisis #2 alluded that Batman had primary control over the systems. The penultimate scene of this week's issue where The Daily Planet's Lois Lane received leaked video confessions from the Sanctuary - signed as coming from "The Puddlers" - could be connected to this idea of a rogue Sanctuary A.I.
The originally-released Heroes in Crisis #3 solicitation framed the issue as a battle between Superman and Booster Gold, and Batman and the Flash teaming up to investigate the mass murder.
"The Man of Steel versus…Booster Gold?! Superman finds out the hard way that Booster can be a formidable opponent when his back’s against the wall. Of course, being the prime suspect in a superhero massacre and exposing a secret trauma hospital for metahumans will do just that. Meanwhile, Batman and the Flash combine their detective skills to investigate what went awry at Sanctuary and uncover a serious glitch in the system—not to mention an explosive, spoiler-ific secret!"
This is the second change for this issue, following an announcement in September that Lee Weeks would be replacing series artist Clay Mann on this issue.
The solicitation text for January 2019's Heroes in Crisis #4 remains the same as originally solicited currently.
