so basically it would be something like this? http://segaretro.org/Power_Base_Converter

Yes, but no.

The patent suggests a flat expansion module that would slide onto the back of a console.  It would look like it was a part of the console and blended into it, rather than an obtrusive lump. 

The module idea never really made sense with the PS2 backward compatibility in the PS3, because if Sony wanted to put the effort into it they could have developed software compatibility, however with the PS4 and PS3 backward compatibility is an intelligent and elegant solution.

Sure the patent is somehow different - just wanted to show that most "new" ideas have been engineered long ago and are not new ideas. Not offending, of course. And I have to disagree: A PS3-hacker once stated that a full-feature emulator on PS3 but i can't find the link now.

 

But read this: http://wololo.net/2012/11/13/has-sony-resumed-ps2-emulation-on-the-ps3/ especially the "sum up".
