Looking to get your hand on the first Dragon Balls on the PS3 and Xbox 360? Atari has a demo up on Xbox Live right now for Dragon Ball Z: Burst Limit, the series' first foray onto the current crop of cutting-edge consoles. The demo weighs in at under 500 megs and features two battles from the game's story mode, Goku versus long-haired guy and other long-haired guy versus those little green things. Yep, I am definitely up on my DBZ terminology. The demo is currently available on Xbox Live and should be up on PSN later today, Sony willing. While you wait, a metric ass-ton of screenshots.

The Consumerist printed a letter from a reader, Grant, who claims his Xbox Live gamertag, "theGAYERgamer," was banned from Xbox Live. When he called Microsoft customer support, a rep reportedly told him that while she wasn't offended by his gamertag, "the greater Xbox community" had found his it offensive, thereby warranting a ban.

Hit the jump for Grant's full letter to The Consumerist and for comment from Microsoft reps.

If Microsoft follows the same schedule it did last year, the Spring system update for the Xbox 360 should be right around the corner. Today, an alleged and wholly unconfirmed list of changes included in the "Q2 2008" update was sent to us, supposedly forwarded from an internal source. The full list—which is after the jump—features about 80 new feature additions, tweaks and changes but was purported to be incomplete and subject to change.

Some are simply interesting as curiosities, such as an option to purchase Xbox Live memberships for charities and the addition of a Media section for audio delivered through feeds, such as podcasts. Others sound more feature robust, such as Windows Live Mail integration and an expanded "Inside Xbox" with news, weather, entertainment, help and community features.

Perhaps the most interesting additions are "Calibration options for motion sensor devices" for the Dashboard and "Support for titles to store installation data on Storage Device for faster loading" for Games. If true, the former would lend further credibility to frequent rumors that Microsoft is planning to introduce a motion controller for the Xbox 360. The ability to store installation data on a hard drive—as is done with some PlayStation 3 games—would certainly be a welcome option, if that's how the wording should be interpreted. Continue on for the full list of rumored updates.

Hot numbers! We got hot numbers, folks, fresh from the Microsoft sales and marketing team! The company's Gamerscore Blog is stuffed with statistics, revealing that Xbox 360 console sales were up 54% during the week of Grand Theft Auto IV's release. Of the millions of copies of GTA IV sold, MS says that 60% of those were of the 360 persuasion. Take that, friendly competition!

In addition to sexy percentages, Microsoft has whipped out big, big numbers, including 1 million concurrent Xbox Live users, 12 million GTA IV Achievements and 2.3 million total players going online last week with Rockstar's latest. All those zeros! *pant pant* I need a cigarette, a Vitamin Water and a shower. For even more digits, hit up the official boast post or visit your local library.

From the Obvious Files comes news that Grand Theft Auto IV has unseated Xbox Live chart topper Call of Duty 4 as the title with the most unique users on the service. That's a lot of dead pedestrians! Liberty City has never heard this many racial slurs and synonyms for "homosexual" in such a short timeframe, we guarantee it. Former Live activity darling Halo 3 settles for third place from April 28 to May 5—and we predict for months to come—as the GTA IV masses flood the service in its debut week.

Taking the number one spot in the Xbox Live Arcade top ten? Brain Challenge! Who didn't see that one coming? Probably someone who was unaware that Brain Challenge was released, just like me.

Next week's batch of Rock Band downloadable tracks arrive just in time for the new, officially licensed Rock Band Lip Ring controller, adding extra authenticity to what Harmonix is calling the Scene Pack. Individual hipster tracks will hit you in the wallet for $1.99 (160 Microsoft Points) each or $5.49 (440 Microsoft Points) as a bundle. They're all master tracks, fortunately, and should show up on the service of your choice starting next Tuesday.

DLC Week of May 6th [Rock Band Forums]

Today marks the 25th 35th (oops) anniversary of me popping out of my mother's uterus, and to celebrate, Activision has released a playable demo of the game of the movie Kung Fu Panda for me to play! The 810MB demo features the Jack Black-voiced panda Po taking on the evil forces of the snow leopard Tai Lung. According to Larry Hryb's website, the demo is only available in the US and Canada currently, with other regions getting it closer to the film's release. Kung Fu Panda is due out in theaters in early June in the states, so either they are supremely confident about the quality of the title or figure kids might need something else to play in between bouts of jacking cars and stabbing hookers. Thanks Activision!

I thought it was over, but you folks just keep on buying them. Namco Bandai is readying yet another batch of downloadable planes for Ace Combat 6: Fires of Liberation for release tomorrow via Xbox Live, including yet another gaudy, incredibly expensive (400 MS points) IDOLM@STER model and two planes that really do nothing but shoot colored missiles for show purposes. Along with those three, a cheapy Typhoon and a completely free PJ Emblem F-16C, they're also releasing a 400 point pack containing four aircraft from the Razgriz squadron of Ace Combat 5 fame. Hit the jump for more details on the release, or check out the gallery to see the pretty planes that keep fans coming back for more.
