Its not uncommon for major retailers to take $10 off the regular MSRP of a game in it's debut week, or sometimes offer a $10 giftcard with purchase in an effort to increase sales.
But if there's a lack of sales as well as bad press for major releases, then major retailers will drop the price of games pretty quick in an effort to clear some shelf space... see Haze, which was selling for $39.99 just a couple weeks after its release at most retailers. Check back in a couple of weeks and see if Too Human is still going for full price at most retailers... I think it won't be.

You know I was always wondering why no one ever used the dollar sign for $ony, but then I realized they have no money so it would be pointless.
