All those infos are official including the posts from Insomniac.
Nothing is spoilery. We know the 3 pre-order suits. The Velocity suit was lakcing its powers form I saw before now it was added and it looks quite good. Also photomode was added in that patch
It seems they added another suit for the game.
So fellas don't play without the day one patch.
NG+ isn't included but will come one day.
