Is 'Undead Nightmare' supposed to be part of canon? (SPOILERS)
Clearly they wrap up the Undead Nightmare DLC in a way that would make it seem that they're trying to make it be part of the canon of the original game, as part of an event we just didn't see in the original storyline. Zombie outbreak happens some time after John gets home to his family in the original game, and everything is back to normal before he gets shot by the government and buried.
But, there are a few plot holes with that idea. Uncle gets shot and killed at the beginning of Undead Nightmare, so how could he come back to life for the ending of Red Dead Redemption? Also, at the end of Undead Nightmare it says "a few months later" and shows John buried and says his wife and son are dead as well, how is that possible?
Any insight?
