At the Game Developers Conference 2007, Microsoft announced it will be launching a 512MB memory unit for the Xbox 360 -- eight times the orginal 64MB unit! It's also increasing the official size limit of Xbox LIVE Arcade games from 50MB to 150MB.

With 512MB, Xbox 360ers will now have greatly expanded storage capabilities for gaming on the go, enabling gamer profile and save game data to be stored and transported, as well as LIVE Arcade games and Xbox LIVE Marketplace content.

Not too surprising, but it also give 360ers the ability to download exclusive content from any of the 45,000 Xbox 360 kiosks accessible at retail outlets worldwide. (Ka-ching.)

The 512MB will be avaible next month (estimated retail: $49.99). The orig 64MB will then drop $10 in price $29.99.

For the early birds, a bonus -- the 512MB will be pre-loaded with the hit Xbox LIVE Arcade game Geometry Wars: Retro Evolved from Bizarre Creations Ltd., for a limited time.
