Skyrim - What's New @ GameSpy

GameSpy has a general summary of changes in Skyrim. I can't see anything new but it does offer a broad overview:

The New Rogue: Poor sad, weak bow and arrow. The weapon of choice for ranged players was never very impressive in Oblivion, no matter how good one's skill. But in Skyrim, the bow has become a formidable tool of assassination. Bethesda got the idea from playing an Oblivion mod where skillful players could take down foes with a single arrow. Yes, you too can now perform a one-hit kill with a bow and arrow in Skyrim (depending on the health of your foe and if your skill and equipment – not to mention aim – are good enough). Players will still zoom in to aim, but now, the longer a bow is drawn back, the more powerful the shot will be. And we hate to burst your bubble if you're suddenly envisioning an arrow-filled inventory and a quick conquest of Skyrim, but Bethesda has made arrows expensive and rare in the game. Treat those babies like gold.
In addition, Bethesda has tweaked the stealth system, making it more difficult for enemies to become alerted to your presence, and skillful rogues can sneak up on enemies and pull off one-hit assassinations. Oh, and the rogue's bread and butter, lock picking, has also been given an overhaul to mimic the mechanic found in Bethesda's Fallout franchise.
