I haven't seen any rumors, to be honest. At least not from any source of reliability. A Lois and Clark relationship on Earth-0 is still a long ways away, the status of Clark with Diana aside. He'll be single or given new romantic interests before they go back to that. After a staunch status quo of writing them together monogamously for two decades, they're just not going to go there again not even four years removed from the new continuity. If Clark/Diana were to end anytime soon, of which I doubt, I'd put more stock in the to-be-debuting character of Lee to become his new interest.
Peter and M.J. fans are still waiting 7 years later. Lois and Clark fans have at least that long to wait too.
