Hahahahahhaahahahah! :roflmao: PS3 and Xbox360 are stone age compared to even mid range computers now... Software emulation won't be an issue 
-edit- Hell, we can even do full 30fps H.264 decoding in JavaScript on a web browser now... Something unthinkable 6 years ago!! 
1. every shared memory graphics type laptop (ie under £1000) can't play a single Directx 9c game like Battlefield 2 half a decade ago and just crashes out, and your average PC World £400 tower barely does Crysis in XGA @ 15fps.
2. You may be able to decode 1080p video using Intel I3 2100k for peanuts BUT people buy £150-200 consoles to play 1080p GAMES at 30-60FPS

3. Emulating a 3.2GHZ CELL CPU / Xenon CPU via an i7 or Phenom II @ 3.4GHZ is NEVER going to happen for the same reason the starscream 68k emulator is not 1:1mhz on emulated:host CPU performance
