They prefere to let you experience the game yourself when it comes out instead of just giving you all the info 8 months before release. As for those who play it right now they are testers... that doesnt need explanation. You know what, why do i even bother you are obviously someone who wont realy care about the game you will just play it for a couple of months and then leave it for a new release. If bungie annoys you that much get out of their site, watch only youtube videos about the game and wait until release or better yet completly ignore and never buy this game.
