There are lots of haters out there complaining that lots of PS games sale numbers are from bundles. Well, I wonder if people are going to complain if lots of people trade in their PS3 version to get $25 off the PS4 remastered version, and this would somewhat inflate 1st week sales.
As the trade-in, I think this is good value. You're not going to be able to sell PS3 TLOU more than $25 (except for suckers on Ebay) because you can get this at Amazon for $30. My guess is that PS3 version will drop in price more when the PS4 version comes out.
