Yeah I do not think you are going to be able to find one for a reasonable price for some time. Unless you are very wealthy, I would not get your heart set on one for Christmas.
Lol those gamers made it sad for kids lol. All the adults purchase 360's on like opening days kids think it is still going to be around for christmas lol..
I camped out and got mine on launch date. In fact I camped out with some friends and in all we got 5 of them! A few went on ebay and we have 2 left. We made quite a bit actually.
I was talking to my brother the other day asking if my nephews if they were begging for the 360. He said yeah but explained it didn't make sense to get one now.
Congrats on getting on Polo. You are lucky... Hopefully your ebay sales covered the expenses of the other two and you ended up with 2 free xboxes.
