I was trying to get one for my wifes birthday. For the first week I tried FM, Walmart, Best Buy and Circuit City everyday, then just Fred Myer everyday for the next week. When her birthday came around I just gave her Zelda for Wii and said the system was coming, two days after her birthday a guy at FM said they were coming in tomorrow. I didn't wait in line, just got there early in the morning and got the last one. Still every time I go to Fred Myer I look to see if they are on the shelf and have never seen one.
I can't believe they are so popular still, we have only played ours a few times in the 6 months we have owned it. It's not so much a gaming console as a party console. What I mean by that is, the games and graphics really suck, but party games like Wii Sports, Super Monkey Ball, and Mario Party are fun to play when you have guests over. I bought a bunch of legacy Nintendo games from the Wii store so those are fun, but you can't copy them to external storage and the HD is too small.
When I bought my PS3 I just walked right in and paid my money. Other than sports and fighting games pickings are still slim for it but I got Dirt and I am waiting for Gran Turismo 5 and Resident Evil 5 to come out. Also got the remote control and use it now as a DVD/Blu-Ray player more than gaming. The PS3 Six Axxis controller is actually a motion controller just like the Wii and there are lots of games coming out now to support it.
