Future Patches and Features

Hey so I know there are a lot of things planned for this game, but I can't find any information on some kind of release schedule on these features. Is there anything official? What can we experience until the official launch of the game?

Since they will not patch on a regular basis, I can not imagine they get all these features done by the end of this year(new maps, vaulting, observer mode, match replay, kill cam, optimization...) Did the publisher/developer announce how they will handle the next months until release?
