Most of the leading national teams will have a fair number of personnel changes at player and coaching level following the World Cup later this year, but it seems a safe bet to say that Wales should win their first Six Nations match in 2020.
They come up against Italy, who have now suffered more than 20 consecutive defeats in the competition, in Wales challenge in defence of the Championship title.
The challenge for Italy will be all the more difficult as the match is played at the Principaltity Stadium in Cardiff.
Ireland will play Scotland at Aviva Stadium in Dublin, while England will travel to Paris to play France on the Sunday.
Super Saturday 2020 will take place on 14 March starting with Wales vs Scotland and for the first time the final match of Super Saturday will be on prime time with France vs Ireland.
The 2021 Championship will start on 6th February with Italy vs France and finish on 20th March 2021 with France vs Wales, again.
** Commenting on the announcement, Six Nations CEO, Ben Morel said: “We’ve got exciting plans for the future of the Guinness Six Nations, and this announcement is a key building block.
“As Super Saturday 2019 proved, the drama and spectacle a Guinness Six Nations creates is unique in the sporting world. Other unforgettable occasions this Championship season such as the clash of Ireland and England in Round One and Wales vs England in Round Three will also live long in the memory.
“The 2019 Championship gave us a stunning finale with three teams competing for the title on the final weekend, a brilliant Grand Slam winner, and a unique Calcutta Cup match to finish the Championship off.
“We look forward to developing the Championship in partnership with our Unions, sponsors and most importantly of all our fans over the coming years, and to the next two years of the Guinness Six Nations Championship generating even more excitement than the 2019 edition.”
