Sony has stated that the only way in which SOCOM could be done on the PS3 is due to the included hard drive.

A Sony Computer Entertainment America developer Seth Luisi has been hyping up the power of the PS3 stating that the amount of detail they have packed into SOCOM on the PS3 is absolutely surreal.

He continued by stating that the only way in which what this game has could be pulled off is with the power of the PS3. He stated that it simply is not possible on the Xbox 360 or Nintendo Wii.

He also stated that since all of the PlayStation 3 consoles contain a hard drive, it allows for a lot of data to be accessed much faster.

He stated that this game could not be done on other consoles because...

"SOCOM: U.S. Navy SEALs Confrontation makes full use of the HDD in the PlayStation 3. One of the often overlooked advantages of the PS3 compared to competing platforms is that it contains a 2.5" serial ATA hard drive which allows us to use the Hard Disc Drive for extremely fast data access. Since we can count on the hard drive to be in every PS3 console, SOCOM Confrontation uses a very aggressive data streaming system which in turn allows for much greater detail in the game environments. For this reason alone, the level of detail which you will see in the environments and characters in SOCOM Confrontation is not possible on any other game console.

Take a quick look at the screenshots below for an early look at what we are able to achieve using the hard drive in the PS3. This is still pre-alpha and the quality will continue to improve as we get further into development."
