The latest word is that Café will not have a hard drive.
The Wii follow-up is set to contain eight gigabytes of on-board flash memory and will not use a hard drive, sources have allegedly told gaming blog Kotaku. The new system, which is scheduled to be revealed at E3, may
also use a disc format that can hold 25GB of data.
It is unclear whether the system will be using a blue laser technology similar to Sony’s Blu-Ray format or red laser technology like the defunct HD-DVD format and regular DVD. A dual-layer HD-DVD can hold 30GB of data, while a single-layer Blu-Ray disc can hold 25GB. Additionally, the console is expected to use SD cards for saving. High definition graphics are expected as the system is set to support resolutions up to 1080p.
Eight gigabytes is an increase from the Wii's 512MB of internal storage, and works out to approximately 64,000 blocks in Wii terms.
It is noted that specifications could easily be altered before launch.
