The minimum spec upgrade not only affects ps3 players, but also those playing on older/ outdated system. I remember there being a few posts in older threads from people saying that they're worried they might not be able to play due to not meeting the future minimum specs required.

If anything, I feel like PS3 players have a better bargain since -outside of buying a PS4- they're given a free upgrade for the game and I think 14 days free play?

Wasn't said that PC gaming is not that popular in JPN?
