In response to a dominating marketing campaign, Kinect, the “controller-free” motion control device, has sold out at many traditional retailers. However, consumers can still grab the device bundled with a console, but they’re “thinning at this time.”

WalMart, apparently, has a some of the devices remaining, but a spokesperson warned, “there is going to be very high demand for these products. We will continue to restock throughout the season.”

“We’ve seen a tremendous amount of excitement and demand for (Kinect) and saw lines at our midnight openings around the country,” said Best Buy’s Chris Homeister. “We are currently sold out online, but we continue to work with Microsoft to obtain product shipments now and throughout the holiday season.”

Since it’s announcement, Microsoft have been silent about it motion controller device. That in mind, according to Microsoft, Project Natal will launch worldwide this October — reveals Microsoft Saudi marketing manager, Syed Bilal Tari.

“Project Natal will be launched in Saudi Arabia on the same date it will be launched in the world,” said Tariq. “That is going to be somewhere [sic] in October. We will be in a position to confirm the date after E3, which is in June. But definitely the date is going to be in October 2010.”

Last time we heard, Project Natal was going to sell for around $100, which is quite an affordable price. The condition, of course, is that you already own your Xbox 360 console. Otherwise, you’ll have to buy both the console and Project Natal in order to enjoy motion controlled gaming.

The company is set to unveil its launch lineup of titles for the device next month at the E3 expo in Los Angeles. In which two shows are planned, one separate for Natal’s “World Premiere” and Microsoft’s Media Briefing.

It’s no secret that Epic Games has established a very avid relationship with Microsoft, producing such exclusives as Gears of War and Shadow Complex – both very high sellers for Microsoft’s system, the Xbox 360. However, it shouldn’t come as any surprise that Epic would proclaim themselves as the “unofficial engine” of Project Natal, Microsoft’s upcoming motion-sensing device.

When speaking to Official Xbox Magazine UK in an interview, Mark Rein Vice President of Epic Games talked about the many ways that Unreal technology could be implanted with Project Natal, even going as far as to call it the “unofficial engine” of Project Natal.

“We are going to work with Microsoft to make that available to Unreal Engine licensees who want to make Natal games,” Rein said. “So, if you want to make a game on Natal, you want to get a big head start and use the same tech as Microsoft, come talk to me. We are the unofficial engine of Natal, or maybe the official, I don’t know. In other words, we consider ourselves the ‘economic engine of Natal.’ You want to make money with Natal, come talk to us, we’ll help you.”

Let’s do the math. Natal + ideas = Unreal Engine usage. Sounds good to me.

When grasping his hands on Project Natal for the first time, Konami‘s Hideo Kojima was caught smitten by Microsoft‘s motion sensing technology, he revealed during a Q&A session at the Tokyo Game Show. He told the crowd that he was shocked by the experience of Natal. “I had to restrain myself from telling everyone I met,” Kojima said.

He believes Natal will raise the bar in all aspects of entertainment and allow people to be connected with their machines in a way that we’ve encountered only in science fiction – I think that he was thinking around the lines of Minority Report, or something like that. Even people who are not gamers can be a part of it because Natal is based on intuition, something that will take video games to a whole new level of interactivity.

“Using Natal, I’d like to come up with a completely new game that no one has seen before. I know I have lots of fans that are loyal to me, and I don’t want to leave them behind. So maybe I can come up with a car that can fly, so my fans can follow me…metaphorically speaking, of course,” Kojima said during the Panel.

In an interview with Phil Spencer, head of Microsoft Game Studios, it revealed that Project Natal, a new no controller technology that allows games to be played with ones body, will not only feature a number of games at its launch, but that it isn’t the only piece of hardware they plan to release for the Xbox 360 of its kind.

Although there’s currently no new hardware other than Natal in the works, Spencer mentions that, “It’s not about trying to sell consumers a new piece of hardware at the wrong time, it’s about evolving the platform continuously,” meaning that new hardware is necessary for the 360 to move forward. Basically, adjusting its abilities as a console.

As for launch titles, there have been some hints to some of the games that will be releasing with Project Natal at its launch; the amazing artificial intelligence called Milo that Peter Molyneux debut at E3, and when Microsoft  showcased the power of Natal during their press conference at E3 with the painting and dodge ball games.

However, with Natal’s launch upon us, the public has yet to see any other titles that work with Natal. Could this mean a “Wii Sports” like title that utilizes the Xbox 360′s avatars? Let the speculations begin.
