"City Shrouded in Shadow Granzella." This is the first time I've seen the name Granzella used in anything other than the company name of ex-Irem employees (Of whom contain the creator of Disaster Report). Granzella recently bought of the ip for Disaster Report from Irem and have said sometime in the fall they would announce something about the series. Also if you look at the image from a diffrent perspective it could almost pass for a Disaster Report tease. Look at it like the rpg image is just a billboard for something else, if you look around it you see broken/crumbling columns and whatnot. As for Namco Bandai being a part of it, they may just be publishing it for Granzella.
Here is what I mean, when you look at this it seems to have nothing to do with the image in the middle.
But.. this is just some wicked speculation.
