360 sold software better, because everyone knew the games were better. 360 had a year head start, so obviously, no one was going to wait on the PS3.
However, once the ps3 came out, immediately it was seen how ahead the 360 was, and for pretty much the life of the 360, people more often than not, opted for the better versions of the game.
It's going to be similar now. Some people are going to opt for the better versions of a game (console versions).
If we don't want to admit that some people brought a PS4 to have the better version of games and brought it mostly for the price, then we'd have to admit that last gen, people mostly brought a 360 because of the price, not the better games (which, ironically enough, was what a lot of 360 fans were saying over at TXB for the longest....they wanted the better version of games for the money).
