I'm on PS3 and have had no issues with any of the 8mans so far. Haven't started my Hard Modes yet but other than the damn phasing in Fates I haven't had a problem with the game running. Now when 24mans come...I believe that'll be a completely different story.

Also, it's not a rumor that ps3 players get the ps4 version for free. SE announced that themselves. It's a fact.
