While Infinite was the third game with the BioShock banner, I'd argue that it isn't BioShock 3, and that by design it intentionally exists in it's own parallel state as BioShock ∞. So, if they're going to make another game with the BioShock label it probably ought to be BioShock 3 in my opinion.

It'd be hard to imagine a BioShock game not taking place in Rapture; though I suppose that's exactly what they did with Columbia. But even then, the designers couldn't resist the siren song of Rapture and (spoiler alert for whomever) set the final moments there. And while creating a brand new unreachable city worked for Infinite, if they repeat it again then it'll probably feel stale or forced.

Who knows? I'd be interested to see how they'd pull that off, but I'd rather return to Rapture. After all, what is BioShock without Rapture? It's Prey or Dishonored or some other franchise.
