Next Timewalking?

Do we know when we’ll get the next timewalking week? Obviously we just finished turbulent time ways so I doubt it’ll be too soon but of course right after all of that I get the urge to go back and play through the expansions I missed (MoP-SL). And I’m thinking about waiting for the next timewalking event because of the big increase in rep you get so then I don’t have to farm rep grinds that much.
