UPDATE: Thread has been modified to hold all Xbox One impressions from those of us on VGChartz that are lucky enough to play one at one of these various truck/warehouse tour events.

Remember that story about a warehouse in France for Xbox One demos? Well there is one in Chicago going on right now as well! My buddy is there experiencing Ryse, Dead Rising 3, etc. He says there are signs everywhere saying no photography, but I'm trying to get some photos from him of at least the building or something.
His impressions so far: The Xbox One controller is amazing. Ryse was incredibly beautiful and smooth. Dead Rising 3 was hilariously fun with no loading screens so it made it way more enjoyable than Dead Rising 1 and 2.
He will send me some pics here before he leaves. Apparently it is only going on this weekend, so if you are in the Chicago area, get there now!

I'll update this OP with pics, further impressions as he gives them to me. So far he has been blown away. I'm incredibly jealous of him.
