No such thing as sure
The balance of volatiles in our own solar system is not as neat and easy as you'd like if a "simple" model had caused it, and then there's the evolutionary path that each planet has taken - mostly physical evolution of the atmosphere and hydrosphere, but in the Earth's case complicated by biological feedback.
This new world "ought" to have volatiles aplenty - enough water to dilute that sulphur and avoid acid conditions, for instance. But it "might" not have much or any. Or it "might" have such a superabundance that no volcanoes ever reach the surface of the ocean.
We don't know, but it's sure interesting to think about...
