Ready at Dawn Founder and Chief Technology Officer Andrea Pessino explained today that the massively anticipated PS4 exclusive The Order: 1886 will run with 4x antialiasing, but the developers still haven't decided on the final resolution for the game:

Not set in stone yet, but we do run 4xMSAA which looks spectacular! x800 with AA looks MUCH better than x1080 without : )

He also mentioned that running the game at 1080p without antialiasing would require less hardware resources than 1920x800 with the edges-smoothing option enabled:

To be clear, x800 with 4xMSAA needs more bandwidth than x1080 would, so 1080 no MS would be cheaper.

Pessino is definitely right there: 4x MSAA is definitely a very resource-intensive feature, as any PC gamer can easily testify.

In addition to this, he also gave the reason why the game won't have multiplayer, and it's a quite simple but compelling explanation:

Correct. No multiplayer, it is a single player, third person action adventure game. : )

Better to do one thing well than a whole bunch half-assed. : ) We are trying to make a SP experience you will enjoy.

He finally explained that he doesn't know the details on what trailers and information will be available and when, so may as well stop asking him. His Twitter feed must be imploding.

I honestly don't know yet the details of what will be made available or when, sorry. I am as curious as you are. : )

According to our information, the embargo on what was showcased at the press tour held two days ago in London (and there will be another in the US on the 10th) will drop on the 18th. so we still have a little less than two weeks to wait to see more of The Order: 1886.

Update: Pessino added further information, explaining that the aspect ratio of the game is an artistic choice, and he doubts it'll change at this point.

The aspect ratio is a core artistic choice (frame, FOV, etc), added performance is a bonus but nowhere near crucial

I very much doubt that vision is going to change at this point. The game is built around it. : )
