What is Black Frieza planning?

Finally caught up with the dbs manga and honestly I don't get why after all this time the anime isn't continuing aswell... But anyway, it left me wonder what Frieza's goal is now since he clearly didn't care about finishing off Goku and Vegeta after defeating them in one blow while in their strongest forms, plus we see in the latest chapter that it's been a while since then yet Frieza still hasn't made any move against them, even though Goku clearly tells Cheelai that Frieza is now "Something else" and that he is still impressed by how much stronger he got, meaning Black Frieza is still the stronger known mortal in U7 after defeating Gas who had previously wished to be the strongest to the dragon balls, since even Beast Gohan was showed to merely be on par with MUI Goku who admits to still be nowhere near Frieza's level atm. So now it seems like a good moment for Frieza to attack them, but for some reason he isn't doing it, so I wonder what he might be up to. Thoughts?
