Get ready to step into the hot tub time machine and warp back to late 2005, when the Xbox 360 was new and in short supply. Now just over 5 years old, the console could again be in short supply in the coming months, and so could the Kinect, Microsoft warns.

According to InformationWeek, Microsoft moved 1.9 million Xbox 360 consoles in December alone, with the recently launched Kinect motion control system playing a big role in hitting that number. As a result, Microsoft unloaded inventory in December that was earmarked for January and February.

"In order to keep up with holiday demand in December for Xbox 360 and Kinect, Microsoft pulled units from its January and February production," a company spokesman said.

Microsoft launched the Kinect in November and sold more than 2.5 million units in the first 30 days. Pretty much everyone who wanted one was able to get one, but that won't necessarily be the case for the next couple of months.

According to Wedbush analyst Michael Pachter's numbers, Nintendo moved around 2.6 million Wii consoles in December, edging ahead of Microsoft's Xbox 360 with 2.5 million units and way ahead of Sony's PlayStation 3 (1.2 million units), CNet reports.

Good for Nintendo, right? Not so fast. If those numbers are accurate, it means Nintendo Wii sales declined 32 percent compared to December 2009. PS3 sales also dropped (to the tune of 12 percent year-over-year), while the Xbox 360 exhibited a healthy 91 percent growth rate compared to one year prior.

There's more bad numbers for Nintendo. For the six month period ended September 2010, Nintendo posted a $24.6 million loss, the result of weak Wii and DS console sales. Going forward, Nintendo hopes to gain some ground with its upcoming 3DS handheld console, but with no living room consoles on the horizon, it will be interesting to see if Wii sales continue to decline or have simply leveled out.

The new Onza Tournament and Standard Edition Xbox 360 controllers will give console a gamers a glimpse into the world of Razer, which up to this point has focused entirely on PC gaming peripherals and assorted gear.

Razer says the two new controllers are "built for the hardcore competitive gamer," but how do you do that with an Xbox 360 controller? The Tournament Edition offers adjustable resistance analog sticks that gamers can twist one way or the other.

Aside from that differentiating feature, both versions sport Multi-Function Buttons (MFB) on the controller's shoulders that allow remapping of buttons. Razer pitches this feature not only as a great way to increase efficiency, but also to make things easier for gamers with disabilities who might have trouble reaching specific buttons on a standard controller.

Other features include 4 backlit Hyperesponse action buttons, non-slip rubber surface, quick-release USB connector, and a 15-foot lightweight, braided fiber cable.

Both the Standard ($40) and Tournament Edition ($50) will be available for preorder starting January 17 and will ship later this month.
