The match was among the matches postponed due to the coronavirus pandemic.
Asked about the end of the tournament in the fall, Laporte replied: “Yes, France-Ireland is announced for October 31. ”
Ireland reportedly tried to face Italy in Dublin a week earlier on October 24.
That leaves October 31st as a Super Saturday final, with the remaining match between Italy and England and Wales with Scotland almost certainly taking place on the same day as France against Ireland.
Launch times will likely be delayed due to TV demand.
Wales must choose a venue for their exceptional match, with the Principality’s stadium currently home to a field hospital.
A pitch in England is the most likely location with Twickenham, Tottenham Hotspur’s ground and West Ham Olympic Stadium being considered.
But a lot will still depend on new Premier League fixtures for the 2020-21 season, which won’t be announced for a while.
The best position Wales can finish is third, although fifth seems the most likely.
But the other countries are in the mix of titles.
England and France lead the table with 13 points, with Scotland at 10 and Ireland, who have one game in progress, with nine.
The title winner will come from that quartet, with Wales on seven having beaten Italy but losing to Ireland, France and England.
An official announcement on a revised international window is due to be made by World Rugby on July 30.
An eight-nation tournament involving the Six Nations countries and two others, most likely Fiji and Georgia, has been scheduled for the remainder of an extended testing window.
