when will regular none subscribing joes like me be able to read/see screens of the game?

I believe that it should be on newsstands/in stores January 14.

You can read all about it and discuss it http://www.gamesas.com/index.php?/topic/1155973-the-february-game-informer-cover-thread-xiii/

That said, it's expected to hit retail shelves on the 14th and subscribers should start getting it tomorrow or Sat.
