Sony Making All PS3s Backwards Compatible?
Patent filing for new cell-based emulation engine suggests that all PS3s could become backwards compatible via firmware update.

June 30, 2009 - In an effort to reduce PlayStation 3 production costs, Sony removed the console's Emotion Engine; the chipset which enables the system to play PlayStation 2 software. At first the company left the chipset in a few of its console SKUs, but has since discontinued all hardware variations with the capacity for backward compatibility. While certainly a smart business decision from a logistical standpoint, the move to remove the console's ability to play last generation titles left gamers with substantial PS2 game libraries out in the cold, but a recent patent filing by the company suggests that the feature could be making a comeback.

*keeps his fingers crossed that the emotion engine will be on the ps3 slim*
hopefully hardware emulated like the cechA ps3 version
