Sony have opened up preorders for PS4 games through PSN. Announced via Twitter, PS3 owners can now preorder next gen games digitally. Currently the only titles available for preorder are Knack and Crytek’s free-to-play shooter Warframe. Knack is being listed currently at $59.99 whilst Warframe is being offered for free due to the nature of the game. This does however pose questions as to why a free-to-play game needs preorders but one can assume that it may bump users up a priority download list of some form.

What are your thoughts on the digital preorders? What are your thoughts on Warframe being one of the two games available for preorder? Let us know your thoughts in the comments.
