I don't know if this was a decisionof the shops or Crytek / EA but because more shops lowered the price I was wondering if the advice-price was lowered because of the leak? Also see http://uk.ps3.ign.com/objects/083/083754.html A few days ago the Nano-edition cost $150,-. The fact that the Nano-edition was also lowered made me also think it was a decision from EA (or Crytec) because it is extremely limited and only available for pre-order, so shops will not need to be afraid to have it in stock and not being able to sell it.
I think lowering the price is the best way to tackle piracy. (then again, a new PC-game should then probably cost nor mare then 25 euro in order to really taggle piracy, a console-game 10 euro more)
However, lowering the price was then a to late decision, now the real fans who already pre-ordered have paid the full price.
