It looks like for the Gamestop "collector's edition" deal you are paying $10 for the artbook, cell, and the tin box. Since Capcom is giving away the art book for their preorders, it really can't be costing Gamestop anything to give those out so really you are paying $10 premium for the tin box and cell. I don't value those particular items very much, so I won't be purchasing that version.
It's too bad only a few retailers are offering premiums on this game. What I would like to see would be the game, tshirt, soundtrack, and artbook selling for $50 if you preorder.
Have you noticed that tshirt preorder premium have slowed to a trickle over the past 2 years? I have 30+ gaming tshirts I have collected, particulary during the PSone era. I would usually be inclined to preorder games at full price, if it included a tshirt. Plus the game publisher gets free advertising to boot.
