“Upcoming PC shooter Prey will be available via online distribution in a partnership with Game xStream – a move that echoes Half-Life 2’s recent distribution through Valve’s Steam technology. This high-performance delivery system effectively cuts the traditional retail environment out of the route to market.”
To me, this is good news. I liked the fact of having the game already installed before release. Would have been nice to get a price cut though, since you don’t get a box. At any rate, check out more info here.
