BUFORD - Unless Santa Claus already has an Xbox 360 in his bag, he may not have one to put under your Christmas tree.

Many retail locations across Gwinnett and elsewhere, including Circuit City and Toys "R" Us, don't have Microsoft's sought-after game console in stock.

Many don't even know when the next shipment will arrive.

"I'm not sure when we'll get more. Probably not until after Christmas," said Jess McNabb, an employee with the Buford Toys "R" Us.

He said the demand for the gaming system has gotten so rabid during the holidays he has been verbally threatened. A couple of other customers have needed to be escorted from the store, while others have stormed out empty-handed and frustrated.

"This guy came in and asked, 'Who do I have to rough up around here to get an Xbox?" McNabb said.

With less than a week before Christmas, the buying frenzy has moved online. The Xbox 360, which sells from $300 to $400 retail, was listed on eBay Tuesday as high as $1,500.

The "360" is Microsoft's next generation of its original Xbox, which was released in 2001. The company won't say how many Xbox 360 units it made for the holiday season, but it does say it's manufacturing as many as it can to keep up with demand.

Microsoft also said it's on pace to sell up to 3 million consoles during their first 90 days on the market.

The Buford Toys "R" Us has sold 16 of the game consoles this Christmas, said McNabb, who has an Xbox 360 of his own.

"From the experience of playing it, it's a great system, but I don't know if it's worth all the hoopla," he said.
