I was bummed when I went to my local Target a week and a half ago, saw two Wiis behind the glass, went to find a sales worker to get it out for me, and by the time I got back (sans sales person), two bratty kids and some other dude were already camping out in front of the glass display! Walked away empty handed.
Since then I've been calling all the usual suspects in the area every couple of days, regardless of the status on those sites like itrackr... TRU, BB, CUSA, CC, Target, WM, etc. Finally, a couple days ago I called BB and they said they had three. Got there 15 mins later, and they actually had 4. Next day they were all gone.
Bottom line - call, call, call. Eventually a few will turn up somewhere, and when they do, drop everything and get there ASAP, cause they are still selling like hotcakes.
Oh yeah... and for what it's worth, I think Wii rawks!
