Info: "The speech skill: “There is not a Persuasion wheel. It’s much more simplified. There’s not a mini-game for it.” He declined to describe it until later, however."
Simplified even more then minigame?
Lockpicking:

Info: "Lockpicking: “There is a minigame, but I hate the word ‘minigame’. There’s also a combat ‘minigame!’” [That latter is irony, don't explode.] “You’ve got to have some interaction, not just a die roll.”"
Well at last not depend on player skills only.
Birthsigns:Source: http://multiplayerblog.mtv.com/2011/04/18/skyrim-character-creation-guide/
Info: "Other decisions, like
Birth Sign, have been removed, so players needn't worry about making a game-ruining decision within the first hour."
Game-ruining decision within the first hour?
How about making all Birth Sign useful instead removing them completely?
Does thats hard to release in the first hour thats Altmer Barbarian with The Lady Birth Sign combination was really flawed by design at chargen stage, for thats need hour?
What will be next races?
Make Birth Sign use leveled powers has more options will be much more better way then just complete remove them from game.

Info: "Naturally, he sees us and dives immediately in our direction. As the music rises in volume and urgency, the dragon roars out a word in the dragon tongue and belches a massive gout of flame directly at us."
Source 2: http://www.g4tv.com/videos/52434/Elder-Scrolls-5-Skyrim-Gameplay-Preview/
Info 2: "Suddenly, strong, deep violin notes pull us from our sightseeing, and focus our attention further up the path where a foolish raider has decided he’s lived a rich and full life, and is now charging at us with his sword unsheathed."
Well does thats mean invisible rats thats stuck somewhere in mesh still trigger Epic music, just because somewhere near of player or Battle music will triggered if enemy aware of player presence and now in line sight of player and then will be battle music triggered?
Seasons:

Info: "Seasons don't change in the game, however."
Well maybe there will be different climate in regions so nature will be different.
