Sony Japan to Patent Backwards Compatibility Adapter

From launch date to now, it took a while for the PS3 to gain some heat in sales (but now they are higher than ever). I bought my 60GB Playstation 3 on launch date. It was fully backwards compatible with PS1 and PS2 games. Slowly but surely, Sony made newer models partially PS2 compatible and now the feature is out of their systems completely. If this was due to a cost issue, Sony now has profits coming in from PS3 sales so bring back this feature! I’m sure the desire for it lessens as time goes by but I wouldn’t mind popping in Kingdom Hearts to play once in a while.

Well, reported today from Japanese message boards exploded overnight when Sony Computer Entertainment Japan filed a patent for a backwards compatible adapter. Nice! The device shows it has its own processor, a DVD decoder/emulator, sound processor, and graphic processor.
Although it would be nice to have it built in and not an external device, this is far better than nothing or having to buy a PS2 again. Do you miss playing your PS2 games? Would you buy this adapter if it gave you backwards compatilibty?
