I think it'll be almost another 10 years before we get a Superman project again, honestly. WB is just really wary at this point. Maddeningly, its because of their own missteps, but that's where things look to be nonetheless. Superman's hope live action right now seems to lie in television. If nothing materializes there(be it Hochelin or something else entirely, and no I'm not counting non-Superman ideas like Metropolis), we're in for another long wait while WB/DC focuses on other characters.
So my guess is nothing outside of animation until around Superman's 90th birthday.
