He will die of an explosion on the ship and that will make them go to the planet as i read somewhere.
But looking at Wikipedia Franco was already on there last night, and reading the movie discription,
the only survivor on the hostile planet is David, and reading up on Scott he said these movies will lead up to the events of Alien,
and we will come to find out who made the xenomorphs, so the easiest guess in this it will all be David/Fassbender,
the creator of these creatures, if im correct the xenomorph is or has some robot aspects (i dont know how you call it in English)
in where the engineers failed to create the ultimate weapon, David succeeds.
And the theory of White Rabbit could be close also that the Derelict is on the Covenant and that the cargo hold are the Covenant crew turned into eggs.
Following this theory this could be the ultimate let down of the whole Alien series.
