I can't be 100% sure what he was implying but he certainly wasn't asking for them to make the game run at a constant 60 fps. He, like many of us, have expectations that a console game should run smoothly. If you, as a developer, are not up to that task, that's on you. As a consumer, it is not my responsibility to let game breaking bugs and immersion-breaking performance issues slide. If it's too difficult to ensure a pleasant experience at a game's current state, delay the game or tweak the resolution, graphical effects, etc. to make it work.
Sorry, but his comment really wasn't out of line at all, based on what's been said in multiple reviews and by people who have played the game pre-release. Now, to be completely fair, the game isn't officially out yet. Once Gaffers have their hands on the PS4 version, we can revisit this topic.
