I think what we're going with at the moment is that the only series that takes place in its own continuity is The Wild Storm Vol 1. What we're calling that universe has yet to be decided.

However, versions of Wildstorm characters like Apollo and Midnight can still appear as themselves on Prime Earth. For example, in their own series Midnighter and Apollo Vol 1, that's main universe.

This has happened before with characters like John Constantine, who had his own thing going in Hellblazer as John Constantine (Vertigo Universe) but a different version of him appeared in the main universe at the same time as an unrelated John Constantine (New Earth).
