'Prometheus 2' ('Paradise') shooting locations?

Just thought I'd bring this back up from past discussions.  Where do you think Ridley Scott will go this fall when scouting for principal photography in regards to the Engineers' planet, should they go there in the sequel?

Last year at this time, member HAL9000 mentioned Mt. Roraima and I thought it looked cool as the "surface" of the Engineers' planet.  I am thinking "paradise" looks like the Garden of Eden on the surface, but as you get closer, it is Hell underneath. Or maybe the Garden of Eden part is just a mirage from far away. Either way, if influenced by Giger, I was thinking is more like this, where each picture shows the progression from the surface to the heart of the planet and where the Engineers live...
