The Steam Website has word that Prey will be released on the Steam service today. This solves the problem for owners of the game by way of the now-defunct Triton service (story) who have not yet received their boxed copy (story), and offers an interesting counterpoint to negative comments about Steam from Scott Miller just yesterday (story). Word is:

Prey will be available Thursday, November 30 on Steam for $49.95. Previous purchasers of the retail or downloaded editions of Prey can activate a copy on Steam at no cost by using their existing product key.
