The official release of World of Warplanes was initially scheduled for September 25 and 26, however, the game launch has been postponed till November 12th (or 13th depending on your time zone). The development team said that they need the delay in order to be certain that they can offer their players a rich and immersive multiplayer experience when the game ships.
In the same announcement, the developers also said that when World of Warplanes goes live, experience points earned during the open beta will not be reset. Instead, the total sum of experience points you’ve earned on all warplanes, will be evenly distributed between the pilots of the tier I warplanes.
