Wilson has scored six goals in his first seven Premier League appearances for the club.
Asked if he had expected the frontman to settle as quickly as he has, head coach Bruce said: "We hoped he would, that was the idea, and that's why we did what we did, to take away that element of getting to know the Premier League. He's been in and around the Premier League now for a good few years.
"He's done very, very well. He's settled in very well because it's never easy to be the centre-forward at Newcastle, so fair play to him.
"He's grasped it and looks as if he's enjoying his football at the minute."
