I think the best you can get is an educated guess from the roadmap PDF, which seems to have been updated.

Due to the launch date and Early Access, I'm personally assuming it will be in August even though that doesn't really fit the roadmap exactly. Otherwise, if it's sometime in July then they must be planning a long break between P4 and Early Access/Launch, which is not out of the realm.
