Questions about the lore that was to be...

I really enjoyed the end game lore and the direction incarnates were going. I always looked forward to more dialog from Prometheus.
I looked forward to how the story with the Coming Storm and Battalion was going to play out.
I was looking forward to seeing what lay beyond incarnates (i.e. Ascension?).
If it is at all possible to know these things, I could at least dream about it if even if I can't experience it.
