Campbell scored 11 goals in 18 games, including a hat-trick in the play-off semi-final second-leg tie against Nottingham Forest, since joining from the Foxes in February as he helped the Tangerines achieve promotion.
"What happens next? I can't answer that yet but I had a little word with the gaffer(Blackpool manager Ian Holloway) after Saturday's game and he wants to sign me. I want to come so it is just a case of hoping Leicester don't do something silly," Campbell told the Leicester Mercury.
"But everyone in Blackpool knows how much I love the club - I wouldn't have come back otherwise. We'll see what happens during the summer but I have been so happy to be at Blackpool during the second half of the season. I love the club. I love everybody, all the players and the gaffer.
"I am speechless and just delighted for everyone that we've actually managed to win promotion. But we've deserved it I think. The last 12 games we have been on such a great run and we showed again on Saturday that we deserve to be where we are. I am delighted."
