$60 is cheap but it was expected. Only Sony and MS will dare to increase the price to $70 in next gen. We will see, it depends on the big publishers too.
But I agree with the guy who said it sucks that games drop in price so fast. It sucks to buy a game at $60 and perhaps you don't have the time to play it for a couple of months and all of a sudden discover that it's sold at half price.
