I bought my copy on my lunch break today. Tons of copies in stock including the "Collector's Edition". I can't wait to play it and try it out online. Now I just need to setup my router again.
As for WoW, I was in the Beta test and it was a pretty fun game. Blizzard changed a lot of stuff in the Beta though and it just wasn't as fun as when I first got in. Once the Beta test started to end, I could tell I didn't really like the way the game was headed, so I canceled my Pre-Order.
On a side note, my friend just bought a 51" Big Screen and got a free Xbox with it, so now between him and his roommate they have 3 Xbox's. Next time I got over there, we are going to bring mine over and have a 16 man Deathmatch
