This year, 18 teams played in three host cities with Madrid as the final arena.
By next year, the number of teams will be reduced to 16 and four locations will be hosted.
The two best in the four-team groups will go straight to the quarterfinals.
Abu Dhabi will probably be the capital of the finals.
The other three host locations will be selected after a bidding process, such as at the Olympic Games and World Cup, which begins in January and which will last for six weeks before the winners are announced.
"The squeak is due to Abu Dhabi"
- We screw to improve the format to make it even more attractive to fans.
The final is then played in a neutral arena (Abu Dhabi), says Enric Rojas from the Kosmos group, which is the organizer together with the International Tennis Federation.
It is controversial that Abu Dhabi, the capital of the United Arab Emirates, is supposed to host the final.
The country has shortcomings in democracy and violates human rights.
- I have a feeling after talking to many players and captains and federations that the squeak that we hear is due to Abu Dhabi, says Rojas from the Kosmos group.
It is already clear that Serbia and Great Britain have been awarded two wildcards for next year's tournament.
