Personally, I'm very satisfied, especially with the implementation of perks. Here's an example of what I mean:
"Character development has been changed as well; "class" selection and "attributes" selection are no longer used, and instead of the twenty-one skills in Oblivion (twenty-seven in Morrowind), Skyrim will feature eighteen skills (four of the removed skills are Hand to Hand, Mysticism, Athletics, and Acrobatics). Sixteen skills have been confirmed: Speechcraft, Alchemy, Illusion, Conjuration, Destruction, Restoration, Alteration, Enchanting, Smithing, Heavy Armor, Block, Two Handed, One Handed, Archery, Light Armor, and Sneak.[5] Faster player level increases can be achieved by increasing developed skills. Activating a Guardian Stone will speed the increase of its governed skills.[5] Gaining a level also grants the player level-specific skill abilities and an increase in health along with an option for a greater increase in health, or an increase in magicka or stamina. Each skill has a perk tree, and a player must choose a perk when leveling up. The confirmed perks for Block are: Shield Wall, Deadly Bash, Power Bash, Bash Disarm, Shield Charge, Deflect Arrows, Elemental Protection, Quick Reflexes.[5]" (http://uesp.net/wiki/Skyrim:Skyrim).
Smithing: we can mine, gather resources, create weapons and armor, improve weapons and armor, etc. etc. etc. Have any of you played minecraft? This feature alone has made me hugely excited for Skyrim.
Perks: check out the bolded sentence about the perks for bash. While we may have fewer skills overall, the increased depth of each skill is stunning (to me). In Oblivion, when we leveled up our Block skill, we'd get better at blocking and eventually get some passive buffs (block at the right time and potentially stagger an enemy, etc.). They've expanded this with perks in a more active way: rather than just blocking, you can actively bash with your shield, deflect arrows, or gain passive elemental protection.
All this for what isn't a very exciting skill in the first place. Imagine what sort of perks we'll get for skills like Alteration, or Archery (we know some already), or Sneak.
Sneak in particular seems to have quite a bit of potential. Being in the Dark Brotherhood should be even more exciting.
Based on the above, I'm not worried. What skills we have have more depth than before. Certain games, like Dragon Age II, really did lose RPG elements. It doesn't look like Skyrim is going down that path to me. They've changed the model a bit, but it all seems to be in the spirit of improving gameplay and RPG elements rather than simplifying it.
