Love Ann's reply ... seems a reference to the narrator's introduction to the old radio drama show "The Shadow", which was something like: "What lurks in the heart of men? Only The Shadow knows ... " 😉
She's right. Adobe has a corporate policy to never announce when something may come out until they're about ready to release it. So ... we'll all know when it's going to come out when the official announcement is made shortly before it does.
Typically, "the cycle" for video post processing apps has been to have new versions announced and debuted in demos at the huge NAB show in Las Vegas, normally third week of April. Then the actual release of the shipping version is released between then and early June.
That is speculation ... and is the best anyone can do.
