Genesis, despite Solomir's lack of post count, I know for a fact he studies Diablo lore more extensively than anyone here. If anyone can even qualify for an expert in Diablo lore, it would be Solomir.
Unfortunately, I've yet to finish the last Sin War book. But I would imagine most changes would be things from the first Diablo manual where it discusses a lot about the Sin War and Inarius.
I still have yet to read the Veiled Prophet. But once I do, I hope to skim over the books and manuals and look for any major inconsistencies. I'm willing to bet there aren't even that many; just some key ones is all. But it was nice of Knaak to consider the Diablo community in this matter because that shows they are aware that there are a great deal of us who do care a lot about Diablo lore as opposed to merely the gameplay itself.
Many of us have expressed a great interest in seeing and/or confronting Inarius. If I'm not mistaken, in the first Diablo game he was originally supposed to be one of the bosses but Inarius was one of the many things that was ultimately cut from the game.
I think even though one may be the official lore, while the other is not, that doesn't mean that the one that isn't can't still compliment the official lore.
And since the first Diablo game, the Diablo story has really expanded. There are even contradictions between the manuals for the first two games, but I don't mind so much because I like to try and come up with clever explanations as to why those contradictions exist.
You can even think of it like in Morrowind if you wish. Where there was the battle at Red Mountain and how many different sides have different accounts of what really happened on that day.
