In the past week (my period of browsing these boards) I have seen no different posting behaviour from Pgh than has been exhibited by anyone else. He also spends more time posting assistance to people than anything else.
To return to the topic at hand (there appears to be nowhere to raise such queries about the validity of moderator actions or query bannings and general forum policy - maybe I missed it, I have to speed browse here at work):
And Al. Certain aspects of the Engine will be coded im sure with Doom 3’s dark and gloominess in mind.
I’d say that’s more likely to be in devoting possibly more time and effort than is neccessary to implementing the lighting and shadow etc effects than anything else. So where other parts of the engine might not be as polished (though who’s to say at this point, 'tis just speculation
), it’ll render darkness like no other. 
It’s not like a game using that engine would have to use the lighting/shadow functionality to that extent though. I’m sure brighter areas will look pretty darn good too.
