Worried about it? Nah. After the Daggerfall - Morrowind - Oblivion progression, I just expect it. :shrug:
Daggerfall had so much less depth than Morrowind, it's not even funny in an ironic way anymore. Morrowind's depth is nuanced though, you have to want it, otherwise it'll be lost. I actually felt Oblivion was a step towards the more procedual/blandness of Daggerfall, than a step away from this perceived layer of depth, simply because the world was bigger, or there were a few more arbitrary skills.
Though, before Fallout 3, I would have agreed, and expected Skyrim to be Hurdur style like Oblivion/Daggerfall, but Fallout 3 returned the sense of persistence, culture and detail that was sorely lacking from Oblivion. Daggerfall I can't fault, because I don't think technology allowed the depth and detail of Morrowind/Fallout3, much less on such a large scale.
Over-designing games is something that worked when you had to compensate for the inability of technology to capture a player's interactions with the game. A perfect game will have just as much design as is needed, with no redundancy built in. New Vegas is a good example, it's not bogged down by the "RPG" just reinforced by it, I said good example, not perfect.
