I don't think it will last that long.
It's simply not based on economics. At some point, even Saudi's are going to want to an ROI, which I don't think that tour will deliver. The things that make it attractive now are also the things that make it unstable.
Too few tournaments, 3 rounds, no points for winning. Once the initial money grab flows through, what are you left with? They are either going to have to alter it to better monetize it, which will make it less attractive or they are going to have to be willing to lose lots of money to keep it going.
I doubt the latter will be that attractive an option at some point.
