He's not opposed to bringing back old Monsters as such but does think most of the Villians should be new.
RTD had always planned to bring back the iconic villians one (or two) a series (Autons/Daleks, Cybermen, The Master, Sontarans/Davros) and always used them as the Big Bad of the series
Moffat does not believe that is necessary anymore and says he will only bring back old villians if he can do something new with them (storywise or effects wise).
So while I'm sure we will see old Monsters back under Moffat we probably won't see them as much and may well get new Monsters for the series finale.
