•Min. 20 units per store.
Should be, but I wouldn't guarantee this to anyone. We were supposed to be getting Minimum 10 60 Gig PS3's per store.
We're getting two. (and two 20 gig units too)
But my store is actually getting twenty Wii.
•Slips given out in line to insure everyone waiting gets a Wii(starting at 8pm Nov. 18th)
Officially, the tickets are not supposed to be handed out until 10 PM. Unofficially, some stores will hand them out early, some stores won't hand them out at all.
•Cameras and Extra security will be on hand to prevent "cuts in line" (Maybe only in Philly?)
Per-store basis. In fact, I doubt there will really be extra cameras.

•Some people are already in line (at last count 5 in line for PS3, 1 for Wii)
Wow. I'd hate to be that 5th person in line... wonder if he'll get one.
We got our first Wii game in today. I took a picture, but I'm too lazy to upload it. It was Happy Feet. Still no word on when the accessories and what not are coming in, but it appears we only have 17 regular controllers coming in.
I said it before and I'll say it again, I think the controllers are going to be much harder to get than the systems...
