MG 1 and 2 possible remakes

I also wonder how Miller would react to us going against the Big Boss/Venom. Will he feel remorseful for helping us take down his former comrades? Or maybe for him it's an attempt to take his revenge against Big Boss.

Did Miller ever actually find out that Venom wasn't Big Boss? I don't remember off the top of my head but either way it has such a huge impact on Miller's relationship to Venom. Two individuals abandoned by the man they trusted with their lives. Miller was fooled into putting his faith in someone who was a lie the whole time. Miller's thoughts and doubts could make for great codec moments (another reason I think the gameplay should be more like the classics than MGSV-Optional codecs are a great opportunity to tackle some of the retcons and changes without it bogging down the main 'point' of the story).

I think Miller knew this whole time about the truth. You can see him reacting to medic waking up in Ground Zeroes trailer. I also like to think that he felt super tense and uncomfortable throughout the main game because of his guilt for hiding the truth from our character.

This is something I'm still not fully sure on. This to me suggests it had to be later on and that Ocelot told him, likely some time after Big Boss and Venom's hospital escape. I'm guessing a while after Kaz was rescued he began to notice "Big Boss" didn't seem right. This conversation could have even been far later on before the end of the game.
