There has been some rumbling about perks in V since FO3 came out, but you may or may not have noticed in oblivion that there actually were perks. THey just didn't appear in a list that you selected from. Instead, your character automatically received perks once skill levels increased past 25, 50, 75 etc. Example: acrobat skill once after a certain point, cant remember what level off top of head, allowed you to use dodge moves like side rolls and back flips. So, TES had perks before FO3 came out, so there really isn't any thing un elderscroll like about perks.
