The PS3 and Xbox 360 are certainly making a splash what with all the advancements in doodad and gizmo technology. Microsoft may have a few months to establish some customers, but Sony looks to have the advantage in terms of tech specs and cool looking hardware (always a bonus). 

To hammer home why you need a PS3 the day it comes out here is a must see video of the upcoming Killzone 2 using IN GAME footage.  Un-effing-believable.
