Tons of rumors out there about the announced films from WB. Even films like Cyborg that are years away. Nothing at all about a solo Superman. If it was really in the works I'd think there would be some rumors. The rights to Superman go public in 2032. Anyone can use the character at that point. Why would WB spend hundreds of millions to do Superman solo films when they lose hin relatively soon. better invest in films for other characters that won't go public for a long time I'd think.
