I'm not expecting much myself. Another Skyrim or Fallout launch most likely.
To give (dubious) credit where it's due though - Bethesda has a history of not providing pre-release copies. Doom is a good example: the press was not given copies before day 1, yet the game came out really good.
(In all honestly I suspect they did that for the very reason to be able to say later: don't panic, all's good, remember, doom was the same)
