Well there is that saying you can't please everyone all of the time. More options is the best way to make the game fun for everyone. The casual player probably does not want to bother with needing to discover stuff themselves an would like to use waypoints or not have to carry a Torch into a dungeon. Where as another player may love this. Just because it was Obsidian who had this good idea first doesn't make it any less good. My only complaint is their hardcoe mode didn't go quite far enough but Bethesda probably has the time to do it right.
New Vegas has a split personality. Which is it -- a post-nuclear RPG or a post-nuclear, hardcoe RPG? It's both. Bethesda strikes me as a group that likes each of their games to have an individual and distinct identity. I think they consider what is best for Skyrim, not what is best for the Elder Scrolls V: Skyrim Normal-Mode and what is best for the Elder Scrolls V: Skyrim hardcoe-Mode. Bethesda is not going to run out of fun ideas for things to implement in plain-old Skyrim, and I think they will focus on making that single mode the best it can be.
