At a fairly heavy-traffic Best Buy and there are only about 30 people in line 5 hours before the midnight release. Supposedly they have about 120 systems available (not sure if that's extra, or includes preorders). Good chance they won't even sell out on night 1.
Funny thing is, they keep asking people what game they're playing first and everyone's like "Mario Kart...there isn't really anything else". Yeah, Mario Kart and a bunch of things we already played/bought years ago that they're trying to sell to us again. "Here's Elden Ring that's halfway between the PS4 and 5 versions!"
