I personally hope that the Saudi dictatorship gets thrown out sooner than later. Saudi-Arabia is the funding source both financially and ideologically for lots of terrorist groups, including Al-Quaeda and the so-called Islamic State.

I don't have any fears about the oil prices - while it's true that Saudi oil is by far the cheapest worldwide, Iran has a lot of growth potential, and the Russians would also like to sell more oil, given their disastruous financial situation.

The real risk after a Saudi collapse, though, is: who is going to take over after a coup, and which regime is set to fall next? And I'm not sure I like the options available...
