Sunday's edgy 2-1 victory over Japan was the last opportunity for Capello's initial 30-man squad to prove their credentials before a cull on Tuesday.
England's manager still has a couple of days to make his decision, but he revealed after defeating Japan that he has already made his mind up regarding the players he will take to South Africa.
Debate has been raging with regards to who will be the unfortunate seven to be axed, but Hart - who played the second half on Sunday - does not think that players have already been told the bad news by Capello.
Asked by Sky Sports News if players knew their fate, Hart said: "Not that I am aware of. It is a tough decision and is something he (Capello) is not going to take lightly.
"But that is why he is the manager and there are decisions to be made."
Capello's first-choice goalkeeper is still a subject for speculation as Hart, Rob Green and David James compete for the starting position.
But Hart insists there will be no ill-feeling among the two shot-stoppers who begin the World Cup as substitutes or squad members.
"All of us are vying for the same spot," said the Manchester City goalkeeper, who spent the season on loan at Birmingham. "At the same time, we have a lot of respect for each other.
"Whoever does get that jersey, I think the other two will be right behind him."
