Maybie Todd decided to add it in for the sake of the fans?
Don't you get it?
This article is based off Pete's twitter: http://www.gameranx.com/updates/id/3001/article/skyrim-allows-you-to-hide-ui-features-new-speechcraft-system/
It says
"Bethesda's Pete Hines has revealed a number of startling new details about Skyrim, including the ability to hide the HUD in its entirety."
The author of the article obviously misread Pete's real twitter answer, that said, very sadly, that finishing moves in any way can't be disabled: http://twitter.com/#!/DCDeacon/status/115860739272605696
In other words, this article source CAN'T be right. Another question though is if Pete is wrong, but since he said in the tweet that he had already confirmed it several times before, I think he's pretty certain.
