The participants were revealed in a video clip. That's what normally happens. There was a difference this year, though.
For the first time in over twenty years, there will be more than twenty participants.
The video initially teased that it would be the usual twenty grapplers with ten in each block. However, the image changed and eight more shadows were added.
I haven't looked into how the blocks will work this time. I suppose it will be four blocks with seven wrestlers in each group and then there will be a playoff between the top wrestlers in each block.
Something similar happened in 2000 when they had four blocks of five wrestlers. I surmise that is what will happen this year albeit with two more names per group.
It's going to be a long summer!
