Does anyone know if there is a limit to the number of field sets per custom object?

I have 250 field sets on 4 custom objects, however with the new capability of creating field sets with fields from child objects I want to roll all the field sets (1000) to once custom object from its 4 child objects for easier changes.

Before I make this effort, I want to check if I will hit any limits, I couldn't find anything on field set limitations in docs.

Does anyone know?

Thanks,
