I would like these rumours to be true since they seem interesting story and character wise.
The idea of the original Jockey not being retconned and being a higher being (to me that's what the rumours are suggesting) is very promising too of course.
Even if these rumours are true though, knowing Ridley Scott, he'll dump 90% of the interesting ideas and will have just made a straight ahead bare bones plotted movie by the time it reaches cinemas.
