That's great news for me as well, I'm more looking forward to the Single Player, as I'm not one for Multiplayer aspects.
Edit:
After seeing that video, and reading a comment off of Reddit, it seems Single Player is limited to some game-play and building up Lestallum as a base. I do hope the story isn't locked behind the online aspect, I just bought a three month PS+ just a few minutes ago just in case so that I can do it's story, I would be disappointed a little, but this could push me into going out of my way a little, although, what if building up Lestallum was the story for Comrades? In Chapter 14, it was a refuge for people.
