I think it's a good idea.
- People who didn't have a PS3 but wanted to play those games have another reason to buy a PS4.
- People who have the game on PS3 have an option at some point to replace it with a PS4 version and not have to turn on their PS3 again. These ports are likely to drop in price quickly, and make it into the PS+ library I think.
- It's not like it has some confirmed down sides. Would you rather have a new Quantic Dream IP in 2017, or Beyond 2 Souls in 2014 AND a new IP in 2017?
