The larger tournaments (EVO, CEO) should be able to afford PC rigs, but I highly doubt locals will be able to afford having multiple PCs with top of the line hardware to run tournaments and turn a profit.

I wonder if PS5 systems will be available for the next gen games. This is outside to scope of this post, but I believe Tekken 8 will be next gen only. I wonder how that will effect how many tournaments will be able to run the game.
