Could Katie Couric's potential new ABC talk show kill 'General Hospital'? That's the latest buzz.

According to TMZ, Couric is close to signing a $20 million deal with ABC. The new deal would entail ABC News and '20/20' specials, fill-in anchoring gigs and a syndicated one-hour talk show. The show would debut September 2012. If that deal happens, ABC is considering giving the hour of programming space 'General Hospital' now occupies back to its affiliates.

'General Hospital' is the third-longest-running soap on the air, and after January 2012, it will be the only soap on ABC. In April, ABC canceled 'One Life to Live' and 'All My Children.' The two soaps will be replaced by lifestyle/talk shows 'The Chew' and 'The Revolution.'
