Information found below comes from the recently leaked documentation by Federal Communications Commission:

– no hardware navigation buttons, only on-screen ones,
– 18.5:9 display,
– support for two SIM cards,
– facial recognition.

Device’s release date is unknown but, judging by the fact that it received FCC certification, should be near. As for its price, Galaxy J4 costs $150, so the Plus variant should not be far off.
