I think that you can't tell from the current tournament participation. The choice of Qatar/Peri could have been motivated by prize fund or not wanting to irritate anyone any more than necessary. I doubt that the WPA can compete with Matchroom in the production of events -- they depend on other promoters and organizations to actually produce events.
Looking at the quality of events produced by the two warring camps tells you who will have the viewers. The money will follow the viewers. The players will follow the money -- and the quality of the production. One example: the commentators at the US Open (except for that one misstep

) and the commentator at the Qatar Open.
