It’s that time again! You know, when we team up with someone, other then ourselves, to host an awesome contest. Anyway, we hear at GamerCenterOnline have teamed up with Pepsi, Harmonix and MTV for a summer promotion unlike any other.

With the launch of PepsiRockBand.com on June 2nd, Pepsi, Harmonix and MTV started a promotion in where the winner will receive an MTV Video Music Award Moonman for “Best Performance in a Pepsi Rock Band Music Video”.

To participate and to enter for a chance to win, gamers have to submit a video of themselves playing Rock Band on PepsiRockBand.com (using their Yahoo ID).

A big part of the promotion are the codes that can be found under the caps of 20oz and 1L Pepsi bottles – they can be played at PepsiRockBand.com and entered for a chance to win either:

• a Rock Band 2 Special Edition bundle (game software, wireless guitar, wireless drum set & mike) every hour, or
• 1 of 5,000 downloadable tracks every day (ends September 13th).

“MTV’s Rock Band has quickly established a new gaming platform that is extremely popular with music fans and gamers alike,” said Ralph Santana, VP of cola marketing, Pepsi-Cola North America Beverages. “We’re partnering with MTV to bring a new exciting twist to the game that will give one lucky band a once-in-a-lifetime experience and a taste of stardom.”

In order to counter the Guitar Hero DS titles, MTV Games and Harmonix have once again teamed up to conquer the video game music scene. But, this time it isn’t on PS3, or even the 360, it seems that they have planned there next Rock Band title for the ‘forgotten handheld’.

Today, MTV Games and Harmonix announced Rock Band Unplugged on the PSP, the first handheld version of the hit band game.

Rock Band Unplugged will allow gamers to take their band on the road and will utilise the PSP’s Wi-Fi capabilities becoming the first PSP game to include a in-game store for downloadable content in North America and Europe.

According to Primotech, who reported the games first details, Unplugged will use the left, up, triangle, and circle buttons to control instruments, switching from instrument to instrument with the shoulder buttons, and playing “phrases” of each instrument to maintain a score multiplier.

Talk about being a bit money hungry, like Metal Gear didn’t make you enough money already. Bloomberg is reporting that Japanese video game creator, Konami has sued Viacom’s Harmonix studio over the well know game, Rock Band. According to the recent complaint, yesterday in a federal court in Texas, Konami demanded cash compensation along with an order that would block Viacom and Harmonix from using the inventions. Some may think this is over the top, but if you ask me this is one case i hope Konami does win.

Harmonix has announced that Rock Band, as we know it, has surpassed the three million copies sold mark. But wait, that’s not all. We also so have gotten word that nearly ten million songs were downloaded since the launch of the game last November. The game will be revealed in Europe on the Xbox 360 in 20 days and on August 29 on PS3, PS2 and Wii.
