They claim some of this information is new, but don't know if it's true. For those wondering about whether they want to read it or not, it doesn't give any outright spoilers such as character motivation or specifics to plot. There is some overview stuff that will give you an idea of what the early game stuff will be like, so if you are hoping to go in completely blind then this is not something you should read. If you want an idea of what the start of the game stuff is like and an idea of how things will go, you will get an idea but nothing concrete. That said…
! An interesting read that gets me excited for the game. Many are tired of the high school setting, but I've played very few games with that setting actually (basically the other persona games are the only ones that come to mind). I'm intrigued at the idea of this other world where they want to make changes, which causes something else to move. I'm guessing this something might be the evil looking protagonist that we saw before. If done well I think the characters will be quite good, as I love seeing characters who don't fit in and are in some ways trying to find themselves.
! Morgana intrigues me a good bit, especially with the hint that it may be using the group. At this time I have enough information and will wait for the game to come out. I will probably ignore any new things to come out, because I don't want to learn much more about the story. If it's gameplay stuff I can work with that.
