Ahead of Saturday's GAA Special Congress, we've been tracking the declared voting intentions of county delegates on Proposal B.
Down is the only Ulster county to pledge its support to the league-based Championship option, with the rest of the northern province expected to vote against it.
Armagh and Fermanagh became the first two counties to declare their intention to vote no on Wednesday evening, they've been followed by. Galway on Thursday afternoon.
In Leinster, Meath, Longford, Kildare, Wexford, and Louth joined Westmeath and Offaly's delegates have all been mandated to support Proposal B.
Laois and Waterford's delegates have a free vote but are likely to vote in favour of change while Kerry and Limerick's delegation will also decide on the day.
On Wednesday afternoon Proposal B gained the backing of GAA President Larry McCarthy and Director General Tom Ryan, though they won't be lobbying delegates ahead of the vote.
McCarthy has urged counties to be bold while Ryan says there's a clear appetite for reform of the All-Ireland Football Championship.
Connacht secretary John Prenty, who was a member of the Task Force which brought forward Proposal A and B, has come out strongly against them - saying it would be "dangerous" to vote them in.
Galway have formally announced that their four votes and a Central Council vote will go no but Sligo, Leitrim and Roscommon will be backing Proposal B on Saturday.
A 60% majority would be required for any change and it's important to note that the county delegates only make up around half of the total ballot.
Central Council, Provincial Councils, Overseas Boards, and past presidents make up a sizeable chunk of the votes on offer while the Gaelic Players' Association holds two votes.
