Arkham Asylum used an older, inferior 3D display mode that is compatible with any standard display. That 3D mode is known as anaglyph 3D, and it uses color tinting to create the illusion of 3D. The left and right views are separately tinted, and then merged back into a single frame before ever being sent to your display. The eyewear worn to complete the effect are color tinted, "passive" eyeglasses.
The PS3 is capable of sending out the individual left and right views for the new 3D in a sequential or "packed" format (two separate views in one frame, either stacked or side-by-side). No color tinting is used, but a 3D TV is required to display the packed frames correctly. Electronically shuttered, or "active", eyeglasses are also required.
There is another technique used in theaters that doesn't require electronic, active shuttered eyeglasses. RealD 3D and Digital Imax project packed frames using polarized light, and the eyewear used are passive, polarized eyeglasses. But this technique is not used in home displays yet, and it still requires a source of frame-packed 3D, not merged anaglyph.
This article explains why older TVs can't display the new sequential 3D correctly: http://www.bigpicturebigsound.com/Can-My-120-Hz-HDTV-Be-Upgraded-to-a-3D-TV.shtml .
Now in theory, they could program Killzone 3 to be viewed in the cheap anaglyph format compatible with any TV and colored cardboard and cellophane eyeglasses. But this is unlikely, Sony wants to impress people with their 3D capability, not just rehash an older, failed technique.
