PS3 SKUs compared, no PS2 backwards compatibility found

PS3 under a microsocope
It's been at least an hour since Sony has released a new PlayStation 3 SKU, so our friends at Joystiq took the time to take a breath. In that moment, they came up with a handy -- and somewhat startling -- chart that explains which PS3 model has what, including Cell chip size (the more efficient and quieter 65nm vs the older 90nm), USB port count, pack-in freebies, and which ones have PS2 backwards compatibility. It's charts like that remind us that no currently-shipping PS3 comes with HD video cables or PS2 backward compatibility, for better or worse. Hit the read link for the breakdown, and start your fanboy engines.
