When will a demo be released for prey 2

We don't even know if the game is still coming out, unfortunately. So it's a little early for a demo (if there even is one).

Bethesda hasn't talked about the game since October (http://www.nowgamer.com/news/1638267/prey_2_no_update_from_bethesda.html) and haven't given us an update in over a year (http://www.bethblog.com/2012/04/19/prey-2-update/). There won't be a demo. Bethesda never releases demo's for any of their games. There's a pretty good chance we won't be seeing this game again. I think the only reason the forums and Facebook page are still up is just to fulfil some kind of legal obligation.
