Sony's PS3 has struggles moving hardware especially in the North American and US markets. Everybody blames the systems price $399 and $499 for the respective models. I see another reason behind Sony's sales slump in the US. Sony first party exclusives never seem to drop in price.
Lets look at the facts:
Heavenly Sword --> Released September 12th, 2007 --> Price still $59.99
Rachet & Clack Future: Tool of Destruction --> Released October 23rd, 2007 --> Price still $59.99 with a sequel on the way.
Resistance: Fall of Man --> released November 14th, 2006 --> Now $29.99 price was dropped only due to impending sequel.
Uncharted: Drake's Fortune --> Released November 19th, 2007 --> Price still $59.99 with sequel on the way
MotorStorm --> Released March 6th 2007 --> Now $29.99, only dropped due to impending sequel.
Lair --> released August 30th, 2007 --> Still $59.99
Is this what we're left with waiting for a sequel to come out for the price to drop. Look at the 360 and Wii, games tend to drop in price a year after a games initial release. Halo 3 dropped to $39.99 after 14 months, certain Wii first party exclusives have dropped $10-20 anywhere between 10-14 months after released. Why is Sony waiting to drop prices on these titles. My point is people looking to buy a PS3 would love to buy more games with it. If games were $29.99 you could purchase two versus spending $59.99 for one. People are turned off that the best games on the system which are all over a year old are still selling for the prices of new releases. By the way I own 4 of the 5 games I listed.
