This is something that bugged me since they started doing it back in Oblivion. Previewing Monsters, NPCs, Items, Weapons etc etc on the load screens. I don't want to see a monster I'm yet to discover until I meet it in the game, not see it on the damn loading screen! Please stop doing this on load screens! It's like the annoying guy in the seats behind you at the cinema that's already seen the movie and describing the plot as you watch it telling his friend what's coming next.
I've already seen a dozen different things I've yet to discover in-game and have the surprised spoilt due to seeing it on the load screen. I think there was a mod in Oblivion to actually remove them from load screens if I remember correctly due to people complaining about the same thing.
