No, it's very unlikely they will.
They hopefully will either announce the three acts who received the most votes OR they could eliminate seven acts until there's three left. A bit harsh, but at least there's no hints as to who was currently in the lead.
Then they could re-open the three phone lines for the three contestants and give a final reminder. A brief chat to each contestant and the judges before closing the lines for the final time and announcing the winner.
