Bring back PS3 full backward compatibility!

We, as PS3 owners, demand Sony to bring back FULL backward compatibility for all PS3 models. A lot of us who bought a PS3 (with no backward compatibility) haven't played PS2 games. Games such as God of War 3, Metal Gear Solid 4, Devil May Cry 4, Killzone 2, etc. you would need to play the original games that were for the PS2 (Games like God of War I and II, Devil May Cry 1-3., Metal Gear Solid 2 and 3, and Killzone 1 were all for the PS2). It wouldn't cost Sony a penny, since now you can possibly bring back full backward compatibility through a firmware update. Also, it could be possible to bring PS2 classic games on the Playstation Store. Please do this. I'm aiming for at least 2,000 signatures for this (goal is 5,000-10,000). Also, add trophy support for the classic PS2 games.
