Short answer is Japan. People there still play a lot on PS3 because they don'tvjump on the latest console midel just for the sake of it. PS4 is only begining to have a half-decent pool of games, there was no use having it before for anyone valuing their money a bit when it comes to gaming.


SE will drop PS3 when its playerbase becomes low enough to justify it, not before. Their estimations were around the release of 4.0 (not released on PS3) then support totally dropped around 5.0, but we have yet to get a new official statement on that
