AC Tournaments is still working on the final draws. The format is a little different to previous years - main change is more pre-drawn rounds and no previously stipulated number of games to qualify:

Burridge Swiss with 7 pre-drawn rounds, 4 on Tuesday and 3 on Wednesday.
Those with X wins will qualify for the knockout and those with Y losses will fail to qualify for the knockout stages.
The Swiss will continue on Thursday until we have a knockout field of 16 players (3-4 rounds) (additional games will be arranged for those that are in or out and after extra play).
The final 16 players will play a Bo3 knockout XYZW format with just the X semi and X final to be Bo5 (if most of the day is available for the match).
The plate will consist of 8 players (assuming no withdrawals) and will most likely be played as a single game round robin.

Update from AC Selectors (19/10/22):
1. The event will start with a qualification event rather than a round robin. The format of the qualification is a Pre-Drawn Swiss – following the pre-drawn rounds, once a player has achieved a set number of wins or losses they either qualify or can no longer qualify for the knockout and therefore do not play in the Swiss any further.
2. Due to the way a pure Swiss format works, there is a certain amount of unfairness in that players who win continually get stronger opponents, and a player with an early loss will generally play weaker opponents. To increase fairness, we have pre-drawn the first seven rounds. It has been done in such a way that all the players get a mix of opponents whose world ranking grades average out as close as we can get to the average of the whole tournament.
3. The Swiss (single game matches) will commence on Tuesday 25 Oct and conclude on Thursday 27 Oct. All games have a time limit of 2½ hours. The plan is to play 10-11 rounds, but bad weather may require the manager to modify this.
4. 16 players will qualify for the XYZW knockout.
i. if in a given round, a 17th player has won X games, there will be no further rounds of the Swiss conducted. Those players that won their Xth game in this final round will play off to decide which of them will qualify to be one of the 16 players in the knockout.
ii. if in a given round, too many players fail to qualify for the knockout, any players still competing will automatically qualify, and those that lost their Yth game will play off to decide which of them will also qualify to be one of the final 16 players.
