Previously (ie a month or two ago) if you pre-ordered you had the option of playing betas. The betas are now closed so effectively there is no benefit now.
actually, that is not true. If you preorder the boxed version on the site, it is the 'Collecter's Edition. It is more expensive then the basic one sold in stores, but you get a rook minuture, a desktop design, and possibly a poster and the soundtrack. Neither the poster or soundtrack have been confirmed yet though.
