Sony has quietly filed a patent that appears to reveal that they are planning or at the very least considering the possibility of reintroducing full
PS2 emulation to the
PS3. The PS3 initially shipped with a special chip for this purpose but was later removed in an attempt but Sony in order to cut costs.

The 'plan' is suggested by Sony's American operation recently filing a patent which describes a method by which the PS3s "Cell" processor could emulate the PS2's "Emotion Engine", without the need for special hardware.
Initially the PS3 actually shipped with this functionality provided in the hardware and this was a key selling point (After all backwards compatibility is very key for gamers), but with later revisions of the console the chip was dropped and with it the backwards compatibility of the PS2.
