I picked up a flier in Best Buy tonight wondering if there was any mention of wii: nope, but I laughed at the fine print under the PS3 which was on the front page: minimum 6 per store for the $500, min 20 per store for the $600. No Wii shelf yet, but there were some empty spots.
I asked someone who then asked their manager if there'd be a midnite launch: Nope again, and they suggested the store would be open at 9am and that I get there 6 hours early. When I asked if they'd have maybe 50 or 60 units they said they weren't sure but at least that much (so maybe it's the truth, maybe not).
Then I tried exiting through the In door but they take that stuff really seriously there, so they forced through the right door.
This was in Westminster, CA near the mall and 405 freeway.
