I work at Gamestop/EB and I keep an eye out for game systems and other such things when I'm out.
As far as at work, The Wii, 360 Premium, and DS pink and Red and Black. Guitar Hero 360, & Wii. Have all been sold out for signifigant periods of time. With the exception of the 360 premimum which we sell out of and the next day get a shipment.
Yesterday Toys R Us was sold out of all the items mentioned above, as was Circuit City two Kmarts and a Walmart in my area. (I was helping a friend find a 360 premimum finally got the last one at the other walmart in town.)
Strangely I went back to Walmart Toys R Us, and of course Gamestop/EB today and we had everything back in stock, (We recieved 15 boxes of stuff)
What I find even more promising however, is that for the last week our Wii game stock has dwindled signifigantly. We started out with maybe 75% of the games that the 360 had and were down to roughly 10-15% of what was left in stock as compared to 360.
