Morrowind-2002 release
TES V(Skyrim?)-2012 release
There is a big difference. Most people interested in huge in-depth gameworlds most likely bought Oblivion if they heard of it. Yet I'm sure many people who aren't interested in that type of thing bought it, as well, partially due to voice acting. Less voice acting in an even newer game of the series(6 years newer) wouldn't help sales, reviews, or the trend of people who complain about the newest game. I want Bethesda to stop wasting money on large celebrities, though(how much do you think the 10 minutes of the game where you actually see Uriel Septim VII costs, just because Patrick Stewart played his role?). Wes Johnson is lesser known, isn't he? Yet, he's great. Keep him(the voice actor for the default Imperial male, the Gray Fox, Lucien Lachance, the Arena announcer, and Sheogorath in SI) in the series. Plenty can be done with voice acting. Bethesda just has to do it right.
