After seeing the footage I've noticed a few things.
>The shadow from the lamp post in the top right looks like they've updated that kind of thing ie: it's not just a circle around the base of the post. Maybe the shadows will even change throughout the day, I mean, seeing as the night-day cycle started in GS, they might as well vamp it up for the remakes.
>The pipes along the right hand side of the lab indicate that there is definitely an underground.
>I dunno, this could be wildly of the point but that is one freaky chimney down at the bottom of the screen. It looks like it could be the tail of a statue or something...
