This will be interesting...
As indeed its pretty much always been Logical David would be in one piece for this movie, during the process after Prometheus Ridley Scott did say Shaw would have to at some point put David back together
Ridley did mention i think prior to Alien Covenant maybe months before that David would be back in a WHOLE-NEW way... and before that he said they had something big in-store for how David becomes Whole again.
So who knows what Ridley Scott meant... his comments are always vague and ambiguous so he could mean that Fassbender is back as a Whole New Robot which is Walter...
Since the few on-set reports from the Summer that have now been released since the end of a Embargo that ended March 1st, these seem to claim we will indeed see Davids Head... but then also he would be put back together.
How this happens? I would assume Shaw does a Hash-job and Quick Fix and maybe David finds some-other way to turn this into a better Fix.
I think we can expect a few Surprises and Curve-balls that we have not seen yet, as the trailers have just seemed to hint at a Fan Boys Aliens Flick.... well like a better done... AVP2R minus Predators and set on another World... meets Alien Resurection
