Before anyone comments about why the PS4 can't play PS3 games: I realize it's most likely an issue of the console's infrastructure in that specific instance. However, we know the PS4 can play PS1 and PS2 games on its hardware, yet very few are available, and I don't see why they couldn't just put a damn emulator in the console and let you insert your disks to play those. Not to mention it's hardly the only console with this problem.
